Can you send me the vendor ID, device ID, which region it is and what
is the correct size, please?

They don't, but 2.4.x kernels do.
For XFree, the best solution is probably to choose according to kernel
version:
< 2.2 Use ports to access PCI registers; do the S3 work-arounds
2.2.x Use /proc/bus/pci to access PCI registers; do the work-arounds
> 2.2 Use /proc/bus/pci to access PCI registers, leave all work-arounds
to the kernel.
Also, starting with 2.2.x, the X server should not attempt to scan the PCI
bus for devices itself (as it will probably fail on machines with multiple host
bridges) and use /proc/bus/pci/devices instead.
Have a nice fortnight
