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.
