Can you send your config? I've got a couple of 7043-260s, and could try
out your kernel on one of mine. The thing I noticed is that it doesn't
seem to be trying to init the scsi controller on the machine in the
'newer' config you have listed. I'll have to do a bit of digging
around, but I'll try to get my kernel config to send you.

FYI, I've only run a 64-bit kernel on POWER3 machines like the 260; the
64-bit kernel runs 32-bit userland code just fine, you can use a 64-bit
kernel to run the same exact software that's running on a 32-bit
Power(PC) machine.
