i am *not* seeing this on one of my KVM instances here running HEAD r292065:

pwright at bsd-current:/usr/src % dmesg|grep -i random
random: unblocking device.
random: entropy device external interface
random: registering fast source Intel Secure Key RNG
random: fast provider: "Intel Secure Key RNG"

this is a sandy bridge (E3xxx) Intel CPU on the hypervisor fwiw.
