Wow, that's one big patch, I can't see what it's doing at all.
Can just the relevant fix be isolated?

That is, if it is even relevant?

Hmm.
What I can understand of the patch, it attempts using sysfs resource0
which is only implemented on kernels > 2.6.12 or 2.6.13, so
that's probably your issue.

Can you try passing the following to mstflint (my version):
-d /sys/bus/pci/devices/0000\:08\:00.0/resource0 q
where 0000\:08\:00.0 is the appropriate device?

Does this work with driver not loaded? On which OS-es?
