is the OS you are trying to boot a 10.3 snapshot or stable, or is it 10.2?
If 10.2 this maybe the problem as there are other bits in the bootstrap
process that need to be updated I think. Try building stable, and put it
into a new bootenv, activate it and reboot. Then from beastie select your
10.2 be and see if that works.
