And they call this "enterprise level", anyway, as you said RH has 
backported a lot of stuff from xen-unstable related to VT-d, changing 
completely the old behavior.

In this bug I've found lots of patches:
https://bugzilla.redhat.com/show_bug.cgi?id=484227

There is a bug opened regarding the lack of documentation (how nice, 
release first, document latter):
https://bugzilla.redhat.com/show_bug.cgi?id=531753

This bug relates to this new stuff, but I suppose only the paying 
customers have access to the solution:
https://bugzilla.redhat.com/show_bug.cgi?id=519399

This one shows a problem like mine, I suppose:
https://bugzilla.redhat.com/show_bug.cgi?id=514458

And finally I will read the Xen documentation, since it looks like 
that's the only reference available:
