ACPI is involved in powersaving stuff but it's used for a load of other things
as well. It's used to set up SMP and interrupts, to support those funny
extra buttons you get on laptops, to get information about docking
stations ... It's actually quite a scary and complex piece of technology and
I don't understand it well at all.
I seem to recall that Windows doesn't make it easy to switch on / off ACPI
support, hence switching to an older Xen version that doesn't have it having
installed Windows on a newer version is likely to upset things. Not an issue
for normal use.
Cheers,
Mark
