It helps somewhat. With lapic enabled there is no interrupt load any more, 
but the rate of clock interrupts is doubled compared to what it was with 
master and without lapic - it was ín range of ~250, but is ~500 now. I 
don't like it much as ideally it should get smaller in development ;).

But with patched kernel and lapic _disabled_ a interrupt load is still 
there - now 100% at CPU0. The rate of clock interrupts is ~225.
