I'm not really sure we do, from what I can see TXF is sufficent since
LOD is bogus with MS textures so you can reuse the slot. r600 hw at
least only has one LD instruction from what I can see.
I've already done a good bit of the state tracker for this, I just
need to get a driver I can run it on :-)
