I've had two different kinds of athlon's (K7-2 and Tbird 1.33Ghz) with V3 agp and Matrox G450 agp but both of the times it was on Abit motherboards and I have never ever experienced these problems. I have agpgart enabled and X set to use agp4x on my G450 and still no problems at all with GL apps. I've used different kernels (mostly dev) and been using X 3.x to cvs on them. No GL problems ever related to a boot flag.
I dont deny the existance of the "bug" in linux but it's just strange how a cpu bug is turning up with some people and not others. Perhaps only some chips from all the batches are affected? whatever the case tuxracer works perfectly here.
