I downgraded to 2.6.27 and got the same problem. But then I also downgraded udev, mkinitcpio, lilo, device-mapper, pciutils and hwdetect and reset the defaults on my BIOS and took out pci=assign-busses and then the card started working. dmesg: http://pastebin.com/m68dd0ce lspci: http://pastebin.com/m4c01d354 It's quite a bit different from when I remember it working the other time. The errors on BARs 7, 8 and 9 still show up and the card is on bus 09. However after I did this I updated all those packages to the newest versions except I did so one at a time not all at once. Now I'm up to date and still have this card working. So I'm sorry to bother you with this, the kernel does not need to be patched for this at all. It's either a BIOS problem or a distro problem caused by updating too many packages at once. Either way it's fixed now.
