You might remember over the last 8 or 10 months, I've had problems
with this beast locking up at random. [...] decided to try changing
them to noapic and nolapic.  Then I rebooted.  The console
resolution was fixed and for 3 days now, the machine hasn't locked
up.

The APIC (advanced programmable interrupt controller) is usually set to "on" by default. Setting it to off is only supposed to be necessary on older machines that have bad/buggy IO-APIC implementations. (I remember trying various APIC settings on a motherboard in 2005; nothing helped because the board was badly designed and built by the lowest bidder.) That said, you really don't *need* an APIC on a single-CPU system
It does have a dual core processor. Do I need apic? What happens if I continue to disable it?

Thanks
