Newer Fedora includes rng-utils / rng-tools (it changed names
recently) that can use a system's TPM (Trusted Platform Module), which
includes a hardware PRNG.  rngd can be run as a daemon to get random
numbers from the TPM and feed them into the kernel's entropy pool, for
use by /dev/random.

My Dell servers use this. :-)

Thanks,
