The other part that's important for s3tc with r600g is the kernel. You need a
fairly recent version, IIRC at least 2.6.39 (but you might as well go straight
for 3.0). The GL format setup is done based on the table at
http://source.winehq.org/git/wine.git/blob/04d541c26d4f50af2bf306dc11943bd12b26f233:/dlls/wined3d/utils.c#l611
Getting 0 for internal format pretty much means the required extension wasn't
found, in this case that would be GL_EXT_texture_compression_s3tc. If you run
with WINEDEBUG=+d3d_caps you'll probably see that it's not in the list of
detected extensions in wined3d_adapter_init_gl_caps(). If this is due to the
kernel being too old, it's probably not in your glxinfo output either.
