I misunderstood Nate.  I thought he suggested to put your driver
under /sys/dev/acpi_support.  I was wrong, he only suggested you should
look at for example acpi_toshiba in order to implement some sysctl hooks.

Sorry for confusion.

Well, on the other hand we discuss stuff that don't belong to ACPI,
as for example cpufreq..  I guess we can discuss stuff related to
power management in general.

ACPI still need to go SMM at least for telling the BIOS to switch to
ACPI mode (instead of Legacy).  It's a transitional phase I
believe, but the transition takes a very long time.
