If /dev/urandom doesn't provide high enough quality entropy for your
uses you could consider investing in an entropy key:
They're very cheap - around $30-$60 depending on the number you're
buying and have been designed (by a very nice bunch of engineers! ;) for
exactly the problem you're trying to solve.
Very useful for systems that lack any other hardware rng but require a
constant source of good quality entropy.
