Sorry I was way too quick on the previous.

I've always heard that you can get faster random numbers by generating a 
lot of interrupts.  I usually do something like run 
/etc/cron.daily/mlocate to generate a lot of disk activity.

And, as I said earlier, depending on how random you want your numbers to 
be, you might consider using /dev/urandom, which is a pseudo-random 
number generator and is a lot faster than /dev/random.
