Just boot it using the powerpc-small debian-installer initrd, the same
one Jeremie Koenig used on his oldworld pmac.

My pegasos powerpc motherboard as a standard via south bridge, including
serial and parallel port support. I guess some prep or chrp hardware
also has it, not sure though.

Yeah, see above. But the modular approach doesn't help here, as
apparently it is discover/cups/whatever trying to load the modules while
it should not which cause the problem.

Many modules make unsane assumption about the hardware, and cause havoc.
This is unavoidable i think, since the probing of the needed bit on pc
compatible hardware cause the pmac to die horribly. Also, as i
understand how discover works, it makes a match on pci ids and such, to
detect the kernels that should run.

It should be possible to add a check in the driver though, just to be
sure. Not high priority though
