I a having problems booting a kernel built from sources supped on
20/8/1998. The machine is a 200MHz StrangARM RiscPC with 48MB RAM and 2MB
VRAM which fails as follows.

init subsystems:stacks vectors undefined pmap panic: Branch to never-never land (zero)..... we're dead

boot: howto=00000100 curproc=f016e3e0
splmasks & ipl masks

If I enable ddb the panic tries to enter ddb but the kernel repeatedly
reports that the undefined instruction used to enter the debugger is 
undefined instead of entering ddb.
