Sure. My PegasosII boots with VGA console.

Lots of memory.
I don't know if 1GB was already tested, but 512MB was.

Which bugs did you observe with serial console?

The only problem I see is:
genfb0 at pci1 dev 8 function 0: Silicon Integrated System 300/305 AGP VGA
no address property

This happens when the OFW-tree entry for the display device (your graphics
card) doesn't have an "address" property. This is normal for the Pegasos
OFW, so ofppc/machdep.c will read it from "frame-buffer-adr" instead.

When this also failed you got the problem from above, and genfb cannot
be initialized.

That's a SmartFirmware problem. MorphOS works with it?

Hm. I cannot remember this happened to me, but I have only 256MB.

You could either try to:
- limit your physical memory to 512MB or 256MB
- uncomment the check in arch/powerpc/oea/pmap.c, function pmap_pvo_enter()
- or remove the options DIAGNOSTIC, DEBUG and PMAPCHECK from you config file

At the moment I have no idea how pmap_pvo_enter() could be called during
pmap_pvo_remove().

This will most certainly cause the "no address property" error from above.

That would be very nice! :)

I am confident that we can make it work somehow.
