Workaround available here http://www.thinkwiki.org/wiki/Category:W510 "To enable brightness control in X, append 'Option "RegistryDwords" "EnableBrightnessControl=1"' to the Device-Section of xorg.conf, orginal source: http://www.nvnews.net/vbulletin/showthread.php?p=2204839#post2204839. This may result in a high-pitched whine after lowering the brightness within X. Brightness may not be lowered and raised in the same increments on Archlinux."
