I've the exact same configuration as yourself except I'm using the VGA connector and a different monitor.
When I try 6629 with the default kernel in FC3 it boots into a black screen and freezes the system. I had to either revert to 2.6.9 kernel or to the 2.6.10-rc2-bk1 kernel to get FC3 on this machine (GX280 1G mem) to work.
Is your 6600 GT a PCIe one?
I'm wondering if you also installed the kernel source for FC3 and 2.6.9-1.667 which I have'nt found a way to do yet (either throught apt or an rpm)?

The driver works great for me by the way (Dell GX280, 6600GT, HP L2335 monitor via DVI-D, Fedore Core 3, 2.6.9-1.667).
