You may want to try the old-fashioned way, xorg.conf, at least to get started 
with the larger 1680x1050 if it's on #1, and add the 1600x900 on #2 after 
getting #1 to work. Please see 
http://lists.opensuse.org/opensuse/2012-03/msg00388.html for how I just 
explained getting started only minutes ago for an Intel user using openSUSE 
12.1. It also works on openSUSE 11.4 with the same bad EDID CRT display on a 
system with rv380 ATI video.
