I can tell you that Knoppix supports that card just fine (I have one on the system I'm on now).

I suggest that you might want to read through these threads:

The last two are particularly long but contain information that may help you get you card working. And while floibler in the first thread never posted back to the thread, he did send me a private message on Jan 12, 2005 that my susgestion worked for him and he planned on investigating further. This all, of course, may not apply to your circumstances, but from what you have stated this could be your problem too. Please post back anything that you learn.
