Sorry, I've been busy the past few days....  By the way, the bz link doesn't seem to work on your repository.

Works fine in Windows, and no, this is my only CX18 card.  My only other computers I own are laptops, so I can't really try another machine.

Yes, I have tried switching slots.

Which kernel are you on?  Could I by chance try this on a Fedora LiveCD?  Would that be able to rule this out?
