This updated mkxf86config.sh file lists the highest resolutions in descending order, so you dont end up with a 1024x768 on a screen thats nicer at 1600x1200.
Created attachment 56613 [details] mkxf86config.sh file search for RAWMODES and you'll see the nice sed-foo hack, courtesy of r2d2, the unlucky one around for all my sed questions ;)
Added to CVS as mkxf86config-0.9.1 and marked ~x86.
