I've tried the workaround that GaaL posted with little success.

In my experience, when adding the line "acpi_osi=Linux acpi_brightness=vendor" into the /etc/default/grub file (to the GRUB_CMDLINE_LINUX_DEFAULT" line), the ability to increase or decrease the brightness is removed (i.e. the brightness stays the same, no matter if you hit the brightness up or brightness down keys). On the plus side, the BIOS didn't reset... ;)

Maybe I've missed a step?
