Welcome. 

You have the most interesting time.  Your stuff always seems to come in 
just as I am about to walk away for the day.

I have just gotten SMP working in my tree and that is checked in.

I did the fun thing and am using the apic timer as my timer.  It has
the nice property of working without calibration because it is based
on the FSB clock, which on the Opteron is fixed at 200Mhz.  And as a
very cool thing I have that code compiling both ways.

More later, Good Night.
