'mknod' is your friend.
Something along these lines with proper ownership will get the job done: mknod -m 660 /dev/ram0 b 1 1
cheers,

The strange thing is that in /etc/udev/rules.d/50-udev-default.rules there is a rule for this device:

KERNEL=="ram[0-9]*", NAME="rd/%n", SYMLINK+="%k"

Is it something the devs should know about? Bug report or something?
