I encountered the same problem with my Dell XPS m1330 laptop. It has the nVidia Geforce 8400 GS 128MB video card.
I was able to load X just fine when using the default 'nv' driver, but attempting to use the latest NVIDIA-Linux-x86-185.18.14-pkg1.run driver, or the kmod-nvidia-PAE packaged version, X wouldn't load and I'd end up with a black screen.
This is with a clean install of F11 32bit (using the official DVD install released 20090609).
Kernel: 2.6.29.4-167.fc11.i686.PAE
Adding "vmalloc=128MB" to /etc/grub.conf followed by a reboot got things working. X loaded and glxinfo indicates that direct rendering is enabled.
