So as not to risk dom0 security, we prefer X etc. in an appliance VM.  You 
could optionally enable X in dom0 and post relevant patches though our 
recommendation wouldn't be to enable X in dom0.

I have on occasions tried host S3 on varied environments (with Xen) including 
the ones you mentioned and have had success with host S3, of course with 
appropriate tweaks.

Hmm... I have seen this issue, more so with older versions of Xen.  I would 
recommend starting a separate thread on this mentioning the version of Xen with 
which you now encounter this issue.
