More details are needed. Do you mean the INSTALLATION runs at 1280x768, or is that the final, installed, desktop resolution? Can you go in and manually change it later? If you do a manual installation, does the card/monitor get properly probed then? How many lines/settings do you have in the xorg.conf file in Kickstart now? Tried removing all the ones you don't want?
Unless you're installing this on machines that are all identical, you may have problems with screen resolution. And since you're using RHEL, are you PAYING FOR IT? If so, do you have support, and have you tried using it?
