might be bug in the drm checker.

Dunno how that would happen, but compressed textures should always show up with
a bpp of 1 (with 4 the calculated size will be 4 times as big as needed). I
know there were some bugs wrt compressed textures in that area, but pretty sure
it should be fixed in 2.6.33...
