Description s3734770 2011-03-12 05:12:10 UTC 
I ran the demo mesa-demos/src/glsl/vert-tex and fetch instructions only return memory garbage.

The same problem appears when running games via wine where hardware skinned models are not shown (better: vertices are spread around the whole coordinate system)
Comment 1 s3734770 2011-03-12 09:14:52 UTC 
An additional info: the texture to fetch has float texels and is a luminance texture.

Patch: also regard vs resources

I found the problem:
077c448d184799e0d9ec962013ec784c6a5c1807 did not pay attention at vs
The fix also adds the resource offset to vs

The r600_shader_from_tgsi() change is wrong, but I've pushed the rest.

oh, we forgot to mark it "fixed".
