nforce2 vs. apic

Andriy,

Yesterday I gave APIC a try on my nForce2 based K7 Triton GA-7N400-L
single processor motherboard while fighting a video problem and with APIC
booted 5.3-BETA5 fine (but didn't fix my problem). In case it makes any
difference, I loaded the module from the bootloader.

I didn't try any APIC specific features.
