so the virtual drivers will require PIRQ support in the guest? I was a bit 
unclear on this one. I'm so used to i8259 oddness and limitations that I 
figured you would deliver virtual dirver interrupts as VIRQs -- I'm wrong 
there?

Ah well, more reading. I'm trying to get the console up as Plan 9 is now 
starting the boot process, which in turn is asking me what the root is ... 
but I can't tell it :-)
