I don't know why the kernel in question is syncing to the dom0 clock
except with an offset of several hours.  I'd love to.  However, the
workaround is to echo 1 > /proc/sys/xen/independent_wallclock before
running ntpdate or ntpd.

No progress on the 2.6.23 kernel -- it's hard to see why they'd lobotomize
the netfront driver the way they did when they put it in the canonical
tree.  :-/
