Indeed, half the reason I suggested Phoronix do these tests is to
stimulate more investigation into performance issues.  We've had
anecdotal evidence of performance reductions since Gutsy at least, and
Phoronix presented a good opportunity to get some solid numbers.

I've spoken with upstream about -intel performance previously.  They've
indicated their focus is on the current git version of the driver, and
so would ask that anyone wishing to provide feedback on performance to
first run the git-head version of the driver.  This would enable the
user to update and give swift feedback to the developers on any
performance changes they are experimenting with.

Beyond that, I'd encourage anyone wishing to help improve -intel
performance on Ubuntu to join the ubuntu-x mailing list to discuss it in
additional detail.
