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.
