All the information seems to be on
http://bytesex.org. It looks to me like you need to install video4linux2 (the new version of the linux video driver). For this it seems you either need a very recent kernel version, or you have to patch and recompile your existing kernel. Anyway, full instructions are on the site for doing this and building and installing the driver.
Good luck!
P.S. I saw one report that SuSE works out of the box with this card.
