German DSL-Card

I was using SuSE 8.1 up to now, but I am thinking about a change to RH8
because of several thing I dislike at SuSE's Linux. Now, I own a card
from AVM called "Fritz!Card DSL" which is supposed to be recognized by
SuSE (which is true) and can be easily configured under SuSE (which is
false). Has anybody an idea if this card is working under RH8? A friend
of mine told me that he knows some people using RH8 and this card,
having no probs. But I didn't find this card in the hardware-support
list on RH's site which makes me feel unsure about it.
