Since APM is quite old, Win does acpi for quite some time, and the
hardware is quite new, I would think you would get better times with
acpi. However, apm has much longer supported in NetBSD than acpi so
ymmv. I am not sure what these new CPUs use for frequency scaling.
Some use acpi, some use other means. But you could give an acpi kernel
a try.
