  User has a system with a built-in random number generator that the OS cannot use.

  [Test Case]
  Make sure rng-tools is uninstalled.
  Reboot with this driver, verify that it is automatically loaded. Leave system idle for this test.
  In one terminal, run 'watch cat /proc/sys/kernel/random/entropy_avail', and note that the minor fluctuation in available entropy over time. Install rng-tools, and notice that entropy shoots up and grows at a faster rate than previously.
