What is the status of that? Most applications use HAL as a backend for display brightness these days. HAL still supports the old interface in /proc for the different brightness drivers, though, but the conversion to the new interface is on my TODO and I will do it this week. So userspace should have fixed this soon, so go ahead ;-) Btw, there's a patchset from Matthew Garrett [1] sent some time ago which also converts the asus_acpi, ibm_acpi and the toshiba_acpi drivers.
