I think that Mesa should not advertise s3tc on drivers that don't support
uploading compressed textures.
Some programs try to set the flag which forces advertising the s3tc although
only upload is supported in the hope they can use precompressed textures. In
the case of r600 the feature should not be advertised anyway.
