Qjimbo, as far i know, there's no solution to your problem!
An update, deviato has been helping me via PM, and he recommended this version of the Chameleon PKG: http://www.insanelym...p;#entry1750792
This version has the resolution module, which installed OK (in /Extra/modules/), but the mode is still not working. At boot time when I type ?video the modes shown are all 4:3 modes, up to 1600x1200. No sign of 1920x1080
The Resolution patcher (module or embedded) only works with Intel chipsets up to 900 series.
