The patches only fixed the build-time and installation-time detection of 
  udev to work with version above of 124.

Have no jaunty based box around here to get some impressions of what 
goes wrong in this setup.

Could you check what udev version it has and if /etc/hotplug and/or 
/etc/udev contains xen related stuff?

As udev is in charge of hotplug events on jaunty a
"udevadm monitor" might get you some further details on what events are 
generated.

Check what files get installed in /etc/udev and /etc/hotplug during 
installation. If you find anything xen related in /etc/hotplug remove it 
and check if that fixes your problem.

It would be interesting to know how you install xen...
