I have my X res set at 1280x720.  I do not have any other modes in my
xorg.conf.  I will try adding some more.  I've only had it hard lock one
time with the new board and it took many attempts at agressively bringing up
the guide and dismissing it.  It's _hard_ to reproduce now.  I have a friend
with a simmilar board and setup with the same problem however.  I will be
able to do further testing through him.

Does the guide honor the gui resolution or playback resolution?  I don't
have either set explicitly, but I will try forcing both to my native res.

It hard locks, ssh session hangs until it times out or the machine is
rebooted so sshd can tell the client it's been disconnected.
