I have been working on a fix for tdfxfb, and have had some success - but since I don't have any documentation, it's involved a lot of guess-work. I haven't looked at this for a while, but I could dig out the code again and supply a patch against what I have got so far. Yep, that would be nice. I have already included a voodoo patch, but i suppose it only works for the older voodoos. I have neither specs nor hardware for them though. > As to your other problem, I have two Voodoos working on my Mac with 2.6, so I would expect such a set-up to work on the Pegasos too. On PPC hardware, there should be no problem of conflicting VGA ports since the PCI sub-system can remap I/O ports on the PPC. Mmm, that sounds nice. do you have OF based drivers for them in your mac ? I need to port the pegasos patches to 2.6.x first though. > Actually, there are one or two bugs in the tdfxfb driver which crop up when > using multiple cards - but nothing too serious it would seem. Again, I've been meaning to submit a patch . . .
