If you disable it in the bios, there should be no IOMMU message left in
dmesg. Disabling it on the kernel cmdline leaves a few behind (they
announce that the bios supports dmar).
Meanwhile I've stitched together the patches for libva, can you try the
for-dieter branch at:
http://cgit.freedesktop.org/~danvet/libva-intel/
Also please ensure that you have the latest xf86-video-intel from git
master installed.
Thanks, Daniel
PS: Please don't cut out libva from the cc: list.
