Yes, the compiled shader is too long to fit in the GC2000's state area
reserved for that. I don't know if that's necessary or the compiler
does something crazy with unrolling.

On GC3000 it should work w/ the above, as that hardware can load shaders from
memory ("I-cache") and that patch adds support for that.
