I tried passing the integrated graphics adapter to the Windows domU,
and the monitor goes into standby when the domU is started. If I
enable the virtual graphics adapter, I see that Windows is
bluescreening on boot (this only happens if the Intel graphics driver
is installed). I suspect that the VT-d-related parts of the ACPI
tables are broken because passthrough doesn't work properly for either
the graphics or sound adapters (that, and Xen reports that the
motherboard supports none of the "optional" VT-d features like DMA
