[Xpert]ATI Radeon 8500 on RedHat 7.2?

[Tony Libby]

Installed Linux 7.2, my ATI Radeon 8500 video card was not detected and is not in the driver list.   I tried selecting the generic ATI Radeon driver and various other drivers that I thought might work.  Each time the screen just go blank when I test the video mode.   After booting, startx just blanks the screen and generates a bunch of stuff, of interest is the bit about the ATI Radeon driver.  Of course, 8500 is not in the list.   Anyone have any ideas of how I might get X to work with this card?   Thanks, -Tony
