On the xlr8yourmac boards they have been able to flash Radeon 9100
PCI's for the Mac with good success. Its more powerful then the 9200
(two rendering pipes v.s. one in the 9200). Also SE cards are crippled
by 64bit memory access which is horribly slow in todays games. The
FX5200 PCI will work in any Powermac G3 B&W or latter but not our Old
World Macs without hacking the NVDriver to (according to JoeVT on the
XPF board) support Old World Open Firmware Map In & Map Out functions
(this is why the GF2MX PCI doesn't work). All ATI Firmwares still have
this function (even the 9800). More or less I believe this is because
its easier to leave it in then take it out. Also 128MB cards will crash
when >64MB of VRAM is accessed because the PCI memory allocation is
only 128MB for joint Input & Output (a 128MB Card needs 256MBs). I'm
not very fluent in Forth Code or in OpenFirmware. I'm just going on
what I've heard from JoeVT & a few others so no flamers please.

Food for thought
I notice that PowerColor have a Radeon 9200SE 128mB PCI card -
wonder if it will work in PCI based Macs as well. Or indeed if it's
hackable so it will work.
Also see XFX FX5200 128mB PCI option as well - same questions?
