Since I'm talking to myself (damn timezones...)

Okay I added a hook to Map/Unmap texture around the mipmap generate 
function, however I'm wonder should I just have added a new dd hook,
for this whole GenerateMipmapEXT call and punt it into the drivers..

Intel code has a intel_generate_mipmap function which wraps the mesa one 
so I'm wondering if I really need to be calling this, even though it 
appears to work..
