I try to implement 2nd-init method (Motorola Milestone/Defy/etc) to hijack ramdisk.
With this method, we can change stock ramdisk, and we can boot CM with stock kernel...
Here's KeiranFTW's original thread too:, but I used 2nd-init instead of chroot

So, i'm done with following steps:
Successfully implement recovery and hijack ramdisk...
I can replace ramdisk contents with new one...
I can boot CM10.2, but it has defects:
Kernel and user space graphical drivers are mismatch, screen is yellowish (no blue), and a lots of mdp errors in dmesg, and no boot animation
no radio
there's some problem with /data/ / sdcard mount...

So i call for help, because i've limited time for this project, but it can interesting...

If you want to try it, do the following steps:
get hijack from here:
get CM from source (preferred) or fxp, and delete boot.img from zip (and connected lines from update-script)
(optional) replace jelly.tar and recovery.tar to your device specific ramdisks, if you're on other device than Xperia SP
go to recovery, apply CM, (optional gapps), copy chargemon and hijack.tar to /system/bin and fix rights, and factory reset...
install 4.3 kernel only via flashtool (if you aren't on 4.3)...

Known problem, that you need original kernel modules too, to get wifi working (not tested)

I think, it's mainly CM configuration, but it maybe helps, when CM team starts to use Sony's 4.3 kernel based CM kernel...

Any helps are welcome...

Here's a screenshot about cm and locked bootloader and stock kernel... It's a bit confusing, because when i screenshot it via ddms, colors are fine, but in screen, there's no blue color, only yellow...

I've found that radio/fs problems are selinux related...

EDIT: Current status:
No wifi
No sdcard on /sdcard (only /data/media)
Got baseband, but still no radio
Visible glitches, yellowish screen (aosp <-> caf ?)
