it's the loader that is crashing, not the kernel.
(at least that is what it looks like to me)

maybe reinstall loader from cd?

actually you should be able to bypass the loader using the bootblocks..

teh sysntax is arcane but you get a chance to enter something in the
bootblocks before the loader. (hit space)

replace /boot/loader with /boot/kernel/kernel
in teh string (I think... it's been a long time since I tried this.)
