Hello Andrew,
Seems this problem is on a lot of Asus motherboards, i have a similar (not the
same) motherboard (P5Q-EM DO), and have had the same problem.
But Weidongs recent workarounds in xen-unstable don't disable vt-d anymore but
ignore the RMRR, so if you wish to give Xen and vt-d a try again, I think it
will work for you as well.
