Using Modular Xorg.
I bought a new 1920x1200 tft and had a very hard time getting
it working after googles found some settings for use on Linux.
Eventually I used the modeline calculator from pkgsrc which
gave completely different results than those I'd found on web
and adding these to xorg.conf gives very good result (just a
few pixels overscan along bottom of screen). I've not bothered
to trim the values.

The sync/refresh were taken from mfrs data as were
allowable values to feed into modeline calculator.
I had to find correct -HSync -VSync parameters by
trial and error.
