This is what I have now, but under KDE control center it still hanging on to 1024 x 768 @76hz, which I never ask for. Where did KDE get that from?
How do I force KDE to accept the resolution/refresh rate that are in xorg.conf?

you can try to add something like the following line in the end of Monitor section of xorg.conf:
Code:
ModeLine "1024x768_60" 65.0 1024 1048 1184 1344 768 771 777 806
you can use the another modeline calculator to create these values for you:
http://freshmeat.net/projects/amlc/
there is also an online calculator for this but i already forgot the site. you can try to search in google for it.
