date seems to gain 9sec/hour on my Shuttle/SN41G2/FN41 when using IOAPIC

booted with "noapic" for XT-PIC timer, it stays locked
onto my wristwatch after an hour. If the workaround is disabled,
and XT-PIC timer is used, it matches the "noapic" behaviour -- no drift.

I can't explain it. I think it is a timer problem independent of the
IRQ routing.


ps. when i ran in XT-PIC mode there were lots of ERR's registered in
/proc/interrupts -- doesn't look healthy.
