Hmmm:

Try changing your config file:

Section "Device"
# Some 7500 boards aparently need this option enabled to work - bug
(#62760)
# Option "CrtScreen"
        Identifier  "ATI Radeon 8500"
        Driver      "radeon"
        VendorName  "ati"
        BoardName   "ati"
        BusID "PCI:1:0:0"
        Screen 0 
EndSection

Section "Device"
# Some 7500 boards aparently need this option enabled to work - bug
(#62760)    
        Identifier  "ATI Radeon 7500"
        Driver      "ati"
        VendorName  "ati"
        BoardName   "ati"
        BusID "PCI:0:9:0"
#       Option "CrtScreen"
        Screen 1
EndSection

Works for me with a Radeon 9000, might help -- at least its something to
try.
