:> Though I don't have a system that could do C3 testing, I added a sysctl

:But I have. Without hw.lapic_timer_enable "systat -vm 1" reports ~270 clk 
:interrupts per second on my laptop with rather idle KDE3 desktop. With 
:hw.lapic_timer_enable and hw.acpi.cpu.cx_lowest=C1 it's 0 (as expected), 
:but with cx_lowest set to C3 it's ~2700 and more. Why?
