after the latest update (a day or two ago) i've experience two problems (one mentioned already)
1) my fn up+down don't change brightness
2) when gnome-power-manager dims the backlight, it dims slowly and clunkily and spikes my CPU usage to 100% and makes any playing audio skip

however adding acpi_backlight= video fixes this
but this is a major regression for me
