Of course;-)

That's what I'm almost doing since I have this mobo. I have APICs enabled in 
both kernel and bios, but IO-APICs disabled. 2.5.60 seems to work for me.
The only thing I'd like to get rid off, are those Interrupt errors in 
/proc/interrupts (maybe they are harmless anyway):

            CPU0
   0:     941032   XT-PIC  timer
   1:       1927   XT-PIC  i8042
   2:          0   XT-PIC  cascade
   5:          0   XT-PIC  VIA8233
   8:          4   XT-PIC  rtc
  10:      14946   XT-PIC  ide2, eth0
  12:      29425   XT-PIC  i8042
  14:       7525   XT-PIC  ide0
  15:         36   XT-PIC  ide1
NMI:          0
LOC:     940979
ERR:        914

They won't go away with noapic, too.

With IO-APICs the ERR count would stay at 0. (but then most onboard devices 
wouldn't work)
That's why i asked for that APIC patch in my previous mail.
