What performance difference do you see between APM and ACPI?
Since you're using Windows 2000, it would be possible to switch between both. I believe it's a matter of enabling/disabling it int he BIOS and then extracting the correct HAL file from the i386 folder to c:\windows\system32\hal.dll.
I remember back in the early days of Windows XP that performance took a big hit with ACPI (It puts everything on a virtual IRQ 11), that's why I ask.
