I agree. I was only showing that the bug is in m
That fixes the bug and is nice and minimal, but it doesn't meet my
overhead-reduction goal.
_NEW_TEXTURE triggers piles of work, mostly irrelevant if we've only

Looks like some mail server ate patches 2,3,4,7. I've resent them.
What you're doing in r600_invalidate_buffer is exactly what I'm trying
