I found the tools located here:
"HOWTO: Unpack, Edit, and Repack Boot Images"

to be very helpful.

I wrote a small wrapper script to extract
the recovery image, substitute a new kernel, and re-install it
on the ADP1, which I use for my own kernel testing. I can post
it somewhere if people are interested.

I use the recovery partition instead of the boot partition.
I leave the boot partition alone since this thing is also my
phone and when I'm done debugging I want to get back to
the original code and config easily.
