This patch makes the hw_random driver a little more informative when it is
starting up -
currently, there is no easy way to tell if the driver detected any hardware.
The AMD driver does mention that it found the chip - this adds the same for the
VIA
and Intel sections of the driver.
Tested with an i810-equipped system.
