Are you using the generic OFW drivers or do you have a real PCI
attachment?

If you have a PCI attachment, how did you implement the interrupt
routing?

Is the Pegasos somthing special or is it PReP or CHRP or?
Does the Pegasos have an OpenPIC?

Reason for this questions: I modified the FirePower platform code of
port-ofppc to support the IBM RS/6000 B50 and 43P-150. They are very
similar machines, CHRP with OpenPIC. I think it would be easy to extend
this to a generic support for CHRP machines.

I also have a Motorola PowerStack II. Unfortunately this machine crashes
very early in the boot process. Maybe OFW incompatibilities.

In addition I have a IBM RS/6000 43P-140. This is a PReP machine with
OpenPIC and OFW. It should be easy to support this machine given the
existing PowerStack II and FirePower code. Again, it should be possible
to extend this to support generic PReP machines.

Unfortunately I am not able to boot the 43P-140. Looks like it needs a
very special boot file format.

I am already at single user with NFS root useing the generic OFW 
drivers. This worked out of the box.
