R51 on ubuntu with gnome desktop here.

Yes, the 7500 is not supported by fglrx and even the 9000 was dropped a
long time ago. The open source radeon driver works with this
minimalistic xorg:

Section "Monitor"
         Identifier      "Configured Monitor"
EndSection

Section "Screen"
         Identifier      "Default Screen"
         Monitor         "Configured Monitor"
         Device          "Configured Video Device"
         SubSection "Display"
                 Virtual 1024 768
         EndSubSection
EndSection

Section "Device"
         Identifier      "Configured Video Device"
         Option "DynamicClocks" "on"
EndSection

It autoselectes and loads the correct module/driver. i get a very
smooth 2d desktop and 3d games. But no 3D Compiz. Disable compiz
and everything is fine again.
