[lug] ACPI Questions

[David Trowbridge]

ACPI requires a user-space daemon to control hardware power usage.
However, at this time, ACPI support is very limited due to its recent
introdution and conflicting standards. You also may want to  check with
Compaq technical support (though tech support usually handles linux issues
poorly), to see if the fan works with Linux ACPI, due to the current
limited status of the project and Compaq's participation in kernel
development.
