I've looked into this a bit more. Looks like the token
RADEON_MAX_TEXTURE_LEVELS is incorrectly defined to be 11 in
the current driver. It should be 12 in order to support 2Kx2K
textures. It looks like this can safely be changed from 11 to 12
without a kernel module version change. However, I'm inclined
to save this change for the Mesa 3.5 DRI branch since I don't
want to accidently mess things up in the trunk code.
Kevin or Gareth, does this ring a bell? Is this in fact a mistake
or was there a reason for using 11 texture levels?
