/var/log/Xorg.0.log has the information to debug this.

Apparently, in 2.6.13 the sysfs symbols were marked GPL only.  This
means that the nvidia entries don't make it, so udev can't create the
special files in /dev.

Creating the files by hand worked for me.  I've also added lines to my
udev config, but haven't booted since.  The changes were:
At the end of /etc/udev/links.conf:
# sysfs doesn't play with non-GPL modules as of 2.6.13
M nvidia0       c 195 0
M nvidia1       c 195 1
M nvidia2       c 195 2
M nvidia3       c 195 3
M nvidiactl     c 195 255

At the end of /etc/udev/permissions.rules:
# nVidia
KERNEL=="nvidia*",     MODE="0660", GROUP="video"
