I've had issues with the ASUS P5E-VM DO on the latest (0902) BIOS.  I
had given up trying to get this fixed, so I don't have a Xen install on
there at the moment.

I investigated the problem in May last year and discovered that one of
the RMRR entries had a base address that was greater than its limit
address.  This didn't seem to happen when using integrated graphics.

Let me know if this is sufficient information, or should I be getting
Xen booting again so you can see the log, or perhaps a dump of the DMAR
table is sufficient?

Thanks
