Now configure, compile and install the kernel and reboot into a non-graphical runlevel (2 or 3).
Uninstall and re-install the Nvidia driver. Everything should be fine now. Not extremely stable, but at least you can now switch back and forth between VTs.
Good luck. ;-)
This will work for FC2T2 kernels, but the option will go away altogether when the mainline 2.6.6 kernel comes out with standard 4k stacks when this patch is accepted, if things go according to plan in the kernel developement world. NVidia needs to get on the bandwagon now and come out with a beta driver for the 2.6.6 and future kernels (or better yet, provide an open source driver). A post about such to the fedora-test-list will find plenty of willing and able testers.
