Here is my xorg.conf file and I use ATI Radeon 1100

I'm loading the dri module which is Xorg module to support radeon

Section "Module"
        Load  "dri"
        Load  "glx"
        Load  "freetype"
        Load  "type1"
EndSection


Section "Monitor"
        #DisplaySize      330   210     # mm
        Identifier   "Monitor0"
        VendorName   "SEC"
        ModelName    "3845"
        option       "DPMS"
EndSection

        Identifier  "Card0"
        Driver      "radeon"
        VideoRam    131072
        VendorName  "ATI Technologies Inc"
        BoardName   "RS482 [Radeon Xpress 200M]"
        BusID       "PCI:1:5:0"

Section "Screen"
        Identifier      "Screen0"
        Device          "Card0"
        Monitor         "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport 0 0
                Depth    24
                Modes    "1280x800" "1024x768" "800x600"
        EndSubSection
EndSection


I'm able to use 1280x800

PS: Xorg 7.2 may has a driver for your ATI video card, I hope it will
be released soon.
