Well, i will be very curious to know what guide/HowTo/Method you are following to install the drivers. I have posted numerous times how to install the ATI proprietary drivers which will work accelerated, and this without using the latest version of X.
If ya had read a bit of the subject of the other topics, in particular XFree 4.3 , or maybe Display Drivers on Linux, you will have had a better clue

No, the 3D support of latest released XFree 4.3.0 is not ridiculous. I have it working on LRs Linux ( LFS 4.0 ) and giving me a nice 100 FPS av in quake3 on the sager of course.
Maybe you should comment, as what distro you are using, and what step you took to make your XFree 4.3.0 work......
