I know there's talk of the "right" way to talk to the acpi drivers, but 
even when something like that is finished, I think we'll still need 
something that provides the same API as /dev/apm, just to preserve all 
the tools that know how to use it.  (I'd love to try acpi on my laptop, 
but if I can't even check the battery status it's a non-starter.)
