Fail. So, I'll try troubleshooting with ununtu 9.10 for a few days, if that doesn't work out, we'll try openSUSE. It says it's linux supported, by god, so we'll try every distro out there until someone gets this working.
I have seen a few gentoo users claiming it works in this thread, so I'll put that on the list as well. But so far, for getting this card to work with the proprietary drivers in linux-- the score is:
Failure: 6; Success: 0.
No, I don't believe this is distro-specific at all.
