Agreed. I couldn't decide, and forgot to ask Ken if it would be OK to
remove form Mesa and let the user decide, when he needed, because Ken
explicitly mentioned r600 in two ocasions or more, in our discussion.
That made me thinking that I could remove from GLL_DRV, because a user
needing it would fill up the steps. Of course, Ken is much more than a
user, so, your suggestion is probably the best one. But it would be good
to hear Ken's opinion.
Again, I agree with you, but Ken may provide some better alternative.
