No, they do not. These are internal \_SB.PCI0.PX40.ECD0._Q0E and \_SB.PCI0.PX40.ECD0._Q0F to increase and decrease brightness (these are mapped to the hotkeys in the DSDT), and GPLV and SPLV to get and set it directly, probably designed for ospm (which I use in the driver). > > Search your DSDT for such methods. > Already did so: And none of the methods get hit when toggling the > display brightness.

Well, these might not be obvious to spot. Cross-referencing and indexing help a lot in that. Check for IndexFields with interesting names, perhaps you'll find something anyway.
