I did. My scenario was the following
- host: C5.2/x86_64, fully updated. Needed to run Win XP/32 as VM, with 
full access to the parallel port given to a very special Windows driver 
(which controls a development board)
- in the guest we have to run a commercial tool based on Eclipse  (Java).

With stock xen, I was unable to transfer control of the parallel port to 
the guest. It simply did not see the port, no matter what I have tried
With xen-3.3 from gitco and the same xen config, the port was correctly 
identified and could be used from Windows. On the other hand, Java 
started to consume 99% of the CPU making the VM impossible to use.
