I'm busy with the same issue with froyo. What hardware are you using? I'm using imx.31. My kernel boots up - crashes on init. I'm looking into the eabi tuning (-march TARGET_CPU_ABI etc). I've added printfs and fd-open-writes to the tty device in init.c (/system/ core/init/init.c:void main) -> no debug coming out.
All the android kernel ninjas, what is needed to just get Android's init running?
