If your machine used to work (with 3.0) and does not work with 3.1-rc,
then we need to fix the driver so that, with no configuration changes,
your machine continues to work. Preventing regressions is our primary
responsibility when changing the drivers.

Does reverting Matthew's backlight patch fix a regression on your machine?
