@gidantribal, no, that would require to know what to change. So far I know the in the working kernels, there was a GFX0 object in /proc/acpi/video (and likely that hat the brightness control). The acpidump shows that there should be the required methods to detect the brightness control (although the method to return the brightness levels is incorrect as it omits the definitions for the ac and battery brightness). So I created kernel packages that will print more debug messages.You can find them at: http://people.ubuntu.com/~smb/bug333386/ I tried to supply a modified DSDT but re-compilation of the disassembled DSDT fails for some strange reason.
