Thank you for pointing this out, I corrected the patch to contain
these files as well. Style aside, it basically results in the same code
as kib's patch, so it's redundant now. The only differences are PCI Ids
for chipsets that are not supported yet (that's what I was testing), I
attached a patch for those.
