I guess the default as it is not set anywhere (in linux it can be 
changed only during boot time i think)
Do you have idea how can I see the current timecounter on linux ? :)

This is what I found in dmesg:

time.c: Using 3.579545 MHz PM timer.
Calibrating delay using timer specific routine.. 4416.34 BogoMIPS 
(lpj=2208170)
Calibrating delay using timer specific routine.. 4409.37 BogoMIPS 
(lpj=2204688)
Using local APIC timer interrupts.
Detected 12.528 MHz APIC timer.
Disabling vsyscall due to use of PM timer

I guess this means that ACPI timer or PM Timer is used? :)
