OK, got it.  See Greg's comment about the firmware interfaces and sysfs.

BTW, there is a relatively well placed set of people that also consider
/proc passe, especially new interfaces that use or encourage its use.
Those people stand a good chance of keeping any unjustified expanding
use of /proc out of the kernel.  Is this a concern, or is it more
important to get features into distribution kernels, and leave mainline
until later?
