I initially tried using OpenGL, however mythfrontend crashed every time.

glxgears runs fine however I didn't spend much time investigating why
it was crashing. I'm overseas for a couple of weeks and when I get
back I'll try to find out what is going on and if it's the Intel
driver or myth that is the issue with OpenGL rendering. That same
install (I had the drive in a Lenovo T400 laptop) was working fine
with the Intel graphics in the T400 so it might be the new HD graphics
support that is still lacking.
