Assuming this (http://techsounds.org/xorg.conf) is your log, here's
the problem, your device sections are wrong.  you have this right now:

Section "Device"
    Identifier  "ATI Radeon 9600 XT"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:5:0"
    Screen 0
EndSection

Section "Device"
    Identifier  "ATI Radeon 9600 XT-2"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:5:1"
    Screen 1
EndSection

Section "Device"
    Identifier  "ATI Radeon 9100 IGP"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:7:0"
#   Screen 2
EndSection

the Seocndary device Id is not really a device, it's just a hack to
make multi-head cards work in windows 2000.  for multi-head cards
always use the bus id of the primary card.  Remove all current device
sections and replace with this:

Section "Device"
    Identifier  "ATI Radeon 9600 XT"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:5:0"
    Screen 0
EndSection

Section "Device"
    Identifier  "ATI Radeon 9600 XT-2"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:5:0"
    Screen 1
EndSection

Section "Device"
    Identifier  "ATI Radeon 9100 IGP"
#   Driver      "ati"
    Driver      "radeon"
    BusID       "PCI:1:7:0"
EndSection

Also you have a duplicate Screen section with the same identifier, "Screen 1",
remove that duplicate screen section.

Assuming your busids are corrent that should work.
