It would only make any sense at all with a non-generic kernel driver 
anyway so most x86 are out. Prime examples where this would be useful 
are the sparcbooks ( where I wrote most of the relevant driver code 
anyway and I'd really like to have this under kernel control ) and 
whatever device Garrett s working on ( or rather, anything small and 
mobile ). No need to be overly concerned since this can be implemented 
on a by-device basis.

Yes, backlight levels etc.

have fun
