My xorg.conf is below. This is for the 169.xxx series of drivers and a
pal setup - so you will need to tailor it. Essentially with the newer
drivers, you should just need to put the 3 'modes' that you want in
the screens section and (assuming the driver is happy with them),
these will then be available via xrandr. If you don't know the name of
the modes to use, try 'startx -- - logverbose 6' to get more log
detail on the modes available.

Your bigger problem may be driver issues though. From memory
interlaced modelines were finally fixed again in the 169.xxx series of
drivers - so you may need to upgrade. These drivers have various
issues, including ones with xrandr. You may find that you need to kill
X and restart it to get xrandr working properly.

Other than that, once you have it setup. you may then get sync issues
between the display and mythtv when playing back interlaced material
with an interlaced modeline. Search the lists for 'viktor's bobdeint
patch' for endless discussion :)
