I've already mentioned this in the programming thread; just thought I'd repost it here as of interest to users, rather than developers.

Slashdot comment:

I've recently hacked the 7300/7500/7600/8500/8600 Graphics Driver {archive link and readme} to support resolutions in the 1600x1200 range on a stock PowerMac 8500 (probably works on the other models as well). I now have a 20" 1680x1050 LCD connected and working perfectly, locking on to the analog signal with perfect pixels. I figured out where the timing parameters are stored in the driver, allowing other new resolutions as well (like 1440x900), and fine-tuning of the pixel rate. Even with a CRT, this allows higher resolutions. Contact me {see original post} if you'd like try the driver or have a different resolution.
