Hm. The second patch doesn't seem right, it doesn't help if only the
server supports EXT_texture_from_pixmap. I wonder why this should help
at all, because there won't be a function entry point (unless the used
libGL is just broken and has the function, but not the extension
string).

I'd like to check out the first patch, because ATM compiz is really slow
on Xgl on i915 as well. This used to be *much* better.
