Retested with the latest d-r-t and at at least on my RV740 the new CS checker
code seems to do the job right.

@Dave: Would it be safe now to also advertise the remaining two BC formats in
r600g? The BC4 and BC5 one? Also, is it intended that the s3tc_to_blittable
(and the reset function) take a level parameter, which isn't used inside the
function?

Concerning FEAR: I don't think this is related to texture compression. I
fiddled around with the ingame performance options yesterday and the GPU resets
disappeared when I switched the engine from DX9 level to DX8 level pixel
shaders. Maybe this is related to the GLSL piglit tests that still lockup the
GPU.

Anyway, apart from manually enabling the envvar, this issue looks fixed to me.
