So someone just needs to teach X about using libsmbios on Dell machines.
Just like it's using /sys/class/backlight on Linux. I don't think the X
people are opposed to this; certainly ajax didn't seemed opposed to this
last time I checked.

Yes, I really think X should be doing this. X is _the_ device driver for
UNIX graphics; I don't think it's useful to try and replace it. Plus, X
knows about multiple displays etc. etc.

Yes. I think this needs to be done in X.
