How do I interpret BUSID from lspci ?

[IL Ka]

``lspci`` outputs:
* Bus (PCI controller, called "complex" in PCI-Express)
* Device (physical device)
* Function (each device can have several functions)
00:02.0 means "Bus #0, device #02, function #0".

Xorg uses following notation:
    BusID          "PCI:BUS:DEVICE:FUNCTION"

So, here is BusID for you AMD card:
BusID "PCI:01:00:0".

In many cases you can use ``Xorg -configure`` to get skeleton for your
xorg.conf
