libtxc_dxtn is also installed.
Radeon 6970 using g3d driver.

There's still some alignment issues at small mipsizes thoug

I'm adding an apitrace of RendererFeatTest64 is you want to play with it:
agd5f has commited patches which should fix this
these may also appear in stable branches sometime
It seems to be rendering correctly now for me. Textures and texts that were corrupted are now fine.
