No, the brightness key will still work with this patch. And you get back the eight brightness level. The main problem is that the implementation is really ugly. More work will be required before it can be intergrated upstream I think (detection of broken BIOS must be moved into xrandr, and an API to query this information must be added to xrandr and used by gnome-power-manager). But until then, if it is working for everybody and there is no regression I'l try to get it integrated into ubuntu.
