This is difficult, because once the information used by the random driver
is filtered to the application level, significant amounts of randomness
are lost, because of timing considerations. Real randomness generated
(esp. on a multiuser OS) by timing numbers can't be filtered. The only
way to ensure this is to build it into the OS.

Personally, I agree with the proposal to allow the device to be
configurable, just returning an end of file if it's unavailable.
