[How do I go about getting SL to recognize crossfire video card set ups?]

I have a trio of 6950 2gb video cards to play with for a while, and I'm wondering if there's anyway I can get SL to recognize at least two of them in 2 way 16x crossfire. Any help would be greatly appreciated :)

[Body and clothing textures failing to load]

I've a similar problem, although, it's just my body that's not appearing at all. prim attachments load fine, but the avi itself is, well, invisible!
