I don't see how /dev/random can be called pseudorandom. It uses a fixed algorithm to produce the output, sure, but the amount of output is no greater than the amount of physically random input. It's not just a seemingly-random number sequence with an unknown starting point.
Now /dev/urandom is also more than a pseudorandom number generator, but unlike /dev/random, it doesn't keep track of entropy, so it may dengenerate into a pseudorandom sequence at any time without warning.
