Yes, just using video=atyfb causes the same issue. There is a

BootX/miBoot do it, using video=atyfb (+ all the various gubbins)

video, the same from a quik boot results in garbage.
It does not surprise me at all. It is not the fault of Quik, it is
simply that OF is completely broken on OldWorld PowerMacs. Those
machines were never intended to be booted from OF. It is the MacOSROM
which does all the job of hardware initialisation, thus the correct
behaviour with miBoot. :)
I beg to differ, slightly. Although open firmware is broken in
different and interesting ways on oldworld macs, whichever way you
boot, it's open firmware that does the initial booting step,
irrespective of whether you then go into the ROM / miBoot, ROM /
MacOS or the quik bootloader (or even the NetBSD bootloader, if
that's your thing).
All that's missing for Wallstreets to boot from quik with accelerated
video, it would seem, is a little video hardware initialisation; that
step _should_ be derivable from the ATI documentation. Like I said,
I don't currently have the time to deal with it, so I'll live with
video=ofonly for the moment.
