Well, the problem is that while some parts of ACPI are solely ACPI (like
AC adapter information), others (like processor SpeedStep or throttling)
are closely tied to the non-ACPI parts of the processor. I guess I can
just remove the Info namespace altogether and have Sys::CPU, Sys::ACPI,
etc.

(for a sample of the API right now -

SysInfo::Linux::CPU[0].ghz		=3D> 1.59
SysInfo::Linux::CPU[0].state.clock	=3D> 1600 # Main power state
SysInfo::Linux::CPU[0].state[1].clock	=3D> 1200 # Lower-power state
# Use low-power state for all CPUs
SysInfo::Linux::CPU.each { |c| c.state =3D c.state[1] }
SysInfo::Linux::CPU[0].state.clock	=3D> 1200

If ACPI is not available, things like SysInfo::Linux::CPU[0]::state
never get defined, but SysInfo::Linux::CPU[0].ghz will still work; only
the SysInfo::Linux::ACPI::exists? function will be available otherwise.)
