If you run "lspci" on the machine you'll discover the PCI bus IDs. For
example on my laptop I get this:-

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME,
943/940GML Express Integrated Graphics Controller (rev 03)

Which in xorg.conf would be PCI:0:2:0 and PCI:0:2:1 respectively. It's
not something specific to the card, but the "connection" (as I
understand it).

Cheers,
Al.
