I agree with Peter and Vaidy that a generic capability in the Linux 
scheduler would be wonderful.  But we don't have that today.

Re: this driver in particular...
acpi_pad accepts an ACPI event from the platform and then
does something with it.

Today, ACPI runs on just x86 and ia64, and I'm not aware
of any plans to implement this particularly feature on ia64 platforms.
