I did the decision.
Reasons:
- you need it in some SMP chipsets (i.e. PIC emulation is wrong on
them)
- you need it in some UP chipsets (machines with Promise RAID on
board come to mind).
- new GX chipsets for Intels also need APIC :(((
- APIC mode is _way_ nicer for everything
Problems:
- some machines have a broken APIC implementation (see Dell Inspiron
threads here).

solution, to appear in -21/22mdk:
- APIC is always enabled
- noapic kernel option will mean _same_ behaviour as before
- if you need noapic, send me the output of dmidecode for your BIOS
and I will try to incorporate that information to the kernel
(i.e. you don't need to put noapic anymore).
Is everybody happy with that plan?
Later, Juan.
