Yes, unfortunately we know what the problem is.  For some reason, both the
8254 timer *and* the RTC are not connected to the IO APIC.  We have a hack
that tests the 8254 timer and does a workaround, but we do not yet have
a workaround for the RTC (real time clock) interrupt not working.

Remind me in a few days.  We have this problem at work and I'm tinkering
with something that should probably work around it enough to get going.

Cheers,
