Official X10 Airpad ROM image - SlateDroid.com:
The kernel.img (extracted from the firmware images with the wendal tools) seems to be different.
But it realy looks like a normal kernel

* I stripped the header (8bytes)
* I ran it through a disassembler [loading at c0408000]
* I checks various function entrie points (usbin /proc/kallsyms and the vanilla kernel source)
all functions i check where at the right point

* the method discriped in the rk29xx wendal thread can be used for the kernel to

- using wendal tools extract the kernel.img
- ls -l kernel.img (and note the file size)
- strip header & footer
dd if=kernel.img of=kernel.bin bs=1 skip=8 size=(filesize-12)
- reapply header & footer
rkcrc -p kernel.bin newkernel.img (ps modify rkcrc with correct header tag)
- verify kernel.img newkernel.img

rkcrc recreated an exact copy from the stripped kernel.bin
P.S. 2nd 4 bytes from header is the size

bytes 0..3 KRNL
bytes 4..7 08 bd 7b 00 (little endian) 0x7BBD08 = 8109320 = size of kernel
