Well, that seems to have done it!  After cleaning up all the remaining 
xen cruft from the system, and rebooting last night, the clock seems to 
be rock-solid today.  I guess the moral is if you have any of the xen 
virtualisation libraries or services enabled, you need to be running the 
xen kernel.  I expect the reverse may also be true.
