The Treacherous Platform Module includes an RNG.
Someone (hi Jesse?) should implement support for TPM_GetRandom.
All the specs are public, and the hardware is already in users' hands.
I will not pretend to understand everything mentioned, but having web
searched on "TPM RNG" I came across this:

which may either encourage or discourage depending on one's point of view.
Yep, in theory you can do it in userspace right now, with zero kernel
modifications.
But just my gut feeling about the Treacherous Platform Module makes me
think we should have a kernel driver, for both ease of use, and ease of
replacement should that usage turn out to be unwise.
