They are, and I'm apparently not alone as the last two entries in bug
number 195 are seeing the same problems, and the last entry is even the
exact same machine type (HP xw9300), posted in September. 

I would gladly try some instrumentation if you have any I can turn on. I
will also try the xen-unstable tree instead of xen-3.0.3-testing.

I have a gut feeling that there's something about the way the timer is
wired on this motherboard, as there seem to be workarounds in Linux
kernels for nvidia chipset systems and timers.  But I have no actual
facts to back that up.
