Neat. I always did prefer VIA padlock in userspace.

I just sorta assumed a buffering, interrupt-driver TPM RNG driver would
be better than doing it from userspace, but maybe that was a bad
assumption to make on my part. It should be quite doable to support TPM
RNG entirely via userspace, at any rate.
