None of that is universally correct.  Not every system has an fb0 device,
and even on mine that do, there are no resource entries under
/sys/class/graphics/fb0/device.

Also, the PCI path varies a lot, too.  On one of my systems, it is found
here:

/sys/devices/pci0000:00/0000:00:0b.0/0000:01:00.0

and on another:

/sys/devices/pci0000:00/0000:00:1e.0/0000:04:00.0

None of this works at all on non-Linux systems, for that matter.  (Wine does
run on non-Linux systems, in case you didn't realize that.)
