i use the 1400x900 internal lcd (macbookpro core duo) and a 1280x1024 external 
lcd (analog/vga, no dvi). "big desktop" (i.e. only one screen/framebuffer) does 
not work. i think because of the different resolutions.
but with two screens (not two xorg sessions, but two window manager (dwm) 
instances) everything works fine. here is the relevant part of my xorg.conf:

Section "ServerLayout"
        Screen         "internalscreen" 0 0
        Screen         "externalscreen" LeftOf "internalscreen"
        Option         "AIGLX"            "false"  # perhaps useless
...
EndSection

Section "Monitor"
        Identifier   "lcd"
        Option      "DPMS" "true"
EndSection

Section "Monitor"
        Identifier   "externalmonitor"
        Option      "DPMS" "true"
EndSection

Section "Device"
        Identifier  "fglrx0"
        Driver      "fglrx"
        Option      "ForceMonitors" "crt2,nocrt1,lvds"  # auto monitor 
detection of crt2 seems still broken with 8.33.6
        BusID       "PCI:1:0:0"
EndSection

Section "Device"
        Identifier  "fglrx1"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"
        Screen      1
EndSection

Section "Screen"
        Identifier "internalscreen"
        Device     "fglrx0"
        Monitor    "lcd"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
        EndSubSection
EndSection

Section "Screen"
        Identifier "externalscreen"
        Device     "fglrx1"
        Monitor    "externalmonitor"
        DefaultDepth     24
        SubSection "Display"
                Modes    "1280x1024"
        EndSubSection
EndSection
