I was able to get it to 1440x1080 by entering those mods in the icon info. But not native 1600x1200. I can't stand less than native on an LCD panel!
I wonder if it's a limitation of this 64-bit (128MB) card, made by HIS. I just ordered a 128-bit (256MB) card, a Diamond Stealth 9250. We'll see if that can go native. Hopefully I can return the HIS board.

Add "+RB" at the end of video resolution option:
MODE=1600x1200@60+RB
