Hi, Marek,

Unfortunately I couldn't do it yesterday, but I'll try to do so today. I'm also
entertaining the idea of implementing support for shader disk caching, but I'd
like your opinion before moving forward. I read the implementation on nouveau
and r600 and it seemed simple enough (or, most likely, I'm missing something
fundamental ;)). I don't know how beneficial it could be, though, since
R300-R500 shaders are much simpler, so measurements would have to be done.
