You cannot have both apm and apci enabled. The kernel will build, but
only the one that loads first gets enabled.

From /usr/src/linux/Documentation/pm.txt:

"No sorry, you can not have both ACPI and APM enabled and running at
once.  Some people with broken ACPI or broken APM implementations
would like to use both to get a full set of working features, but you
simply can not mix and match the two.  Only one power management
interface can be in control of the machine at once.  Think about it.."

(This goes for 2.4 and 2.6)

I guess that your MB supports apci (as you have a fast processor on it),
so maybe you could try to disable APM.
