I had my Radeon 9000pro in but the graphics seemed not right. I have Mandriva 2006 and my 3d was working, even though the fps was only about 891fps. Now this was upgraded from my old Rage 128. The question I have is specifically hardware. My motherboard is an older Chaintech mobo running an amd athlon 950. The agp specs says agp 2x. Now the radeon says it has agp 4x and 8x compatibility. Now as I said the 9000 was working but not perfect. in certain graphics, like ppracer, some image maps showed with black dot patterns. Even in Windows games like Warcraft 3 showed blocky, not smooth graphics, even though the rage 128 showed smooth graphics, even if the 3d accel wasn't as fast. I can see that the agp plug for the Radeon is setup different from the Rage 128. Could this cause a problem with the graphics? I get the feeling that the agp on this motherboard isn't high enough to fully support the radeon. I know all the issues with ati cards in xorg and mandriva in particular but specifically wonder about the agp interface.

Then you can only get 2x from AGP. Issue "dmesg | grep -i agp" to see what your kernel did...
