I stand a 120% corrected :)) .... i'll have to just make start() code
position independend as far as it isnt allready...

I've been working on a modified version of `BBBB' to boot NetBSD/arm32
from... Its allmost ready to really relocate stuff and i hope to have it
start NetBSD/arm32 tonight or tomorrow... i doubt it will run though for
i'll have to munge start() and the init_arm() in rpc_machdep.c to account
for the new situation. I've tried to keep as much as BBBB the same so to
ease merging into one bootloader allthough i've only changed the a.out
loader so it wont hurt NetBSD/arm26 loading :)

So work is in progress....

Cheers,
Reinoud
