you might consider a radeon 8500. i find it to be the best for my sawtooth; pretty sure its better than the 9000 even tho its a lower number in its model number and it has the most comprehensive software support/driver support that ive seen for macos9
the problem could be because of hardware differences between sawtooth + later models QS/MDD that the 9000 was made for, does your 9000 have ADC port? thers alot of stuf like that that "kinad works" but not '100% rock solid works" because of differences in design between g4s tahts why some people have no problems at all with their configs and other people have nothign but problems because they are using hardware that, while it is compatible technically, was designed to work with different model specifically;
it was only after years of dealign with that kind of slight incompatibility bullshit headaches that i now lean toward using the actual restore disks for each specific mac aswell.. just to eliminate the possibility of having software/hardware quirks + incompatibilities; when the macs came int he box packaged with the right dvd they were tested + Q&A'd to perform 100% and i believe that they did so via many tweaks + customizations that apply to each specific mac model
your sawtooth was probably made in the latter part of the year 2000 or early 2001. Radeon 8500 is a good fit for it + is leaps + bounds above the rage 128 pro speed + performance + software support wise. the 9000 didnt come out untll yars later im pretty sure.. and it was based on the 8500 pretty sure. cut down version of it.
8500 = r200 chip
9000 = r300 chip? or is it RV250? or RV200?
anyways - i bet you the 8500 would work perfectly
perhaps an even better match would be a first gen radeon or a first gen geforce card
wasnt there a mac driver for the Matrox g400?
i guess im thinking of the promax
