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.
