Are you concerned that because the resolution is not normal-looking that it 
can't be driven at native resolution? If you're not a hacker then this is a 
probably a valid concern but the newer intel grpahics drivers seem to be able 
to drive those chips at more or less any resolution you like with some effort 
in coming up with a suitable modeline. I don't know why this customization has 
to be so hard!

Even though 1280x720 is a standard HDTV resolution, I had a tough job getting 
my intel 845 GPU to talk at 1280x720 - especially over DVI - just because it's 
a non-standard resolution as far as the computer is concerned. It can be done 
though.

My concern with 1366x768 would be that it's not the same as any video 
resolution you're likely to encounter so even 720p will be scaled by a weird 
factor (16/15) unless you can tell myth to output a 1366x768 screen and 
window-box the video in a centred 1280x720 rectangle. I suppose it depends how 
well the 945 does scaling. I'm willing to bet that filling the screen is more 
important than possible scaling artifacts for most people. :-)
