Oh so it looks like this could be "fun" or maybe the other one, so
glsl->tgsi is broken for draw pixels where a texturing is enabled.

The problem is we ignore the fact that texturing is enabled and we
blindly write over the original programs texture info, we also seem to
bind our samplers on top of the original states which also seems
doomed to failure.

I'm not 100% sure how best to solve this, I'll just tool around until
I have an answer unless someone comes up with a better one.

Dave.
