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.
