I'm not sure if this is a permanent solution because /dev is a tmpfs
created by udev on startup (maybe there is your problem?) but you could
try

mknod -m 444 /dev/random c 1 8
mknod -m 444 /dev/urandom c 1 9

Both commands are taken from Linux from Scratch.

There is a static /dev lying on your root-partition. It should have been
created when you extracted your stage3-tarball during installation.
Maybe there is something wrong with that one and udev doesn't create
(u)random when they are not in the static one. To see the static /dev
you must unmount /dev, which you can only do from a live-cd.
