After spending a lot of time looking at the CM7 oc kernel and the samsung source code, I wanted to merge some of the features I think are comparable or interesting. I've got the code I want in place using codebench for Arm11, but now have been trying to understand how to make that into a boot.img. I gave up after working on it all night. After reading about using adb to extract the ramdisk from the phone and merging them ect. Can you guys suggest anything?

Better option: http://forum.xda-developers.com/show....php?t=1241005, blackhawk-tools have automate script to unpack/repack boot.img .

check module local version and make sure it match with kernel local version in defconfig.
also stock ramdisk doesnt enable init.d by default, so u might have problem if flashing onto rom that need init.d script support.

i made local version changes as you said in historical post too...
and about init.d support i was flashing it on stock so that shouldn't have that problem

if its stock rom with stock rfs filesystem u shouldnt have problem. wierd that u had problem

in general this is what need to be done.
1- unpack stock kernel ramdisk
2- cd into module dir in unpacked ramdisk dir, check its local version
3- modify kernel defconfig so its local version matches module local version
4- compile kernel
5- repack output zimage with earlier unpacked ramdisk.

if this should be flash into fresh stock rom with stock rfs filesystem, it should boot.

almost tried it 5-6 times with no boot
progress stops at samsung galaxy ace..
will give it another try later.. even if stock kernel boots i can make further modifications to kernel as i am more interested towards kernel programming rather than rom or app making stuff
