--- Comment #19 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Harder to tell, but I think one of two things is happening:

(a) You have the inverse problem. You're getting a linear texture that's being
interpreted as if it were swizzled.
(b) Uninitialized video ram which happened to be some (set of) textures in a
former life.

I'm tending a bit more towards (b) but not 100% sure. I don't know how you
could end up with linear texture data but think it's swizzled, but I'm also not
extremely well-versed in nv30 driver specifics.
