I started playing with the kernel and the result was surprisingly pretty good(in my opinion),so here it is Remember I'm not an expert or developer, so expect bugs and use at your own risk.

NEWS: Djnilse is making this kernel for cm7 roms.Head over to post #3 and read more.

X8_*WLAN/GDX is for GingerDX v.1-28
X8_*CM7 is new and for "standard" cm7 roms with tiwlan(wifi driver)

-??

Tips
-don't use app2sd script(system/etc/init.d/10apps2sd) when using sd-ext.My phone gets useless with dalvik cache on sd, and I have a class 6 card.Use link2sd instead to free up space, and keep apps you often use on phone.


Thanks
-Free Xperia Team
-Doixanh for helping with wifi driver and for his great work.
-Timpot07 for helping me with testing
-Amrooz for logs and help
-DeFcOn for testing and his great cypress touch-machine.

Final Note
I'm not responsible if your phone goes boom, runs out the door or doesn't behave.
Please stop for 5 seconds and think before you post something smart

Remember to install the update-rom*-AlfsKern*.zip or Kernel AddOn provided with rom

Angry now it's fixed
Alfs Kernel v09c

fixed hitachi bug thanks to the great alfsamsung


Note: Aroma File Manager
the newest version (v9c) includes the possibility to use aroma file manager
AROMA File Manager is full touch File Manager you can use from CWM Recovery
all you need to do is :
  1. download the aroma file manager .zip HERE
  2. Rename the zip to aromafm.zip
  3. put in the root of your SD-Card

Intro

I've been working with alfsamsung for a while now, and together, we managed to port the CWM-Touchrecovery from Napstar to the Xperia X8 (both for cypress and synaptics)

alfsamsung still handels the developemnt, i will handle the releasing of the cm7-version, and maybe a little bit developement, I'm still learning it


What does cm7 version mean ?

so alfs kernel is generally for gingerDX and gingerDX is build from the cm hero sources, but since the x8 has own sources most roms are from build from them.
so the difference between(regarding wifi) that hero uses wlan(.ko) and x8 uses tiwlan(.ko), so wifi will not work
now with two different versions it's not a problem
anymore just take the kernel that fits your rom(gingerdx or cm7)

LibSensorPatch needs to be flashed on MiniCm and roms based on MiniCm
if your proximity sensor doesnt work you can try flashing it, it should solve it


What's new
V09c - 19.12.2012 - 20:41(GMT+1)
- read the changes in alfs changelog
and just for notice, alfsamsung is the great dev here

V09a - 13.07.2012 - 17:23(GMT+1)
- usb connection fixed, thank alfsamsung for the fast update and that he sent me the kernel so i can upload it
i don't have time to build it myself since i'm getting prepared for 3 weeks holidays

V09 - 11.07.2012 - 19:13(GMT+1)
- nothing new for the cm7 version, check alfsamsung's post for the changelog
- be sure to use the newest update.zip patch form alfsamsung's post
and dont forget the LibSensorPatch down here

V08a - 27.03.2012 - 21:13(GMT+1)
- added Eduroam support
- a small update to ext4
- fix for MiniCM7 proximity sensor with old libs of MiniCM7, check attachments
flash it with CWM and have a nice week

This time I made it with NO_FSP_CAP, the other versions was with FSP_CAP enabled, if you got errors like screen tearing, please report, or if it works just fine or is faster than before

V08-v5 - 15.03.2012 - 20:35(GMT+1)
- linked wifi driver instead of copying, should boot up a little faster
- cm9 wifi fix

V08 FIX3 - 07.03.2012 - 07:36(GMT)
- included charger in the ramdisk, so offline charging working now

V08 FIX2 - 03.03.2012 - 15:13(GMT)
- now touchrecovery should work fine for synaptics and cypress (alfsamsung reedited the bootrec)

V08 - 03.03.2012
-CWM-Touchrecovery 5.2.8 for both cypress and synaptics
-new cool touchrecovery buttons (great work from alfsamsung)
-new kernel logo and recovery background (made by myself )
-added options partition sd card and fix permissions
-lof of small changes in the kernel

Big Thanks go to

-Doixanh for helping alfsamsung with wifi driver and for his great work.
-alfsamsung for helping me with the wifi driver
