OK using xrandr was indeed quick and easy.  I added a Modeline to my
xorg.conf then used xrandr to disable VGA-2 and enable TMDS-1 and
magically I had 1080p over HDMI.

Well I have no problem having to RTFM, but I'm not seeing how to do this
in xorg.conf(5) or the i810 manual.  It looked like this was previously
done with the MonitorLayout option, but I believe this ignored with the
new randr stuff.
