sure thing - although to be clear i think the preferred method is to
*not* use a configuration file, so hopefully someone with more info than
me can help determine why BusID detection is failing on your system.
here is an example device section you can drop at
/usr/local/etc/xorg.conf.d/driver-scfb.conf or which ever location suits
you best:
Section "Device"
Identifier "Card0"
Driver "scfb"
BusID "PCI:0:2:0"
EndSection
also, here is my full Xorg as well - although hopefully you won't need this:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
