So, does this somehow indicate that fortuna has attached the
new random device as a source of true randomness?

root at rpi2:~ # sysctl kern.random
kern.random.fortuna.minpoolsize: 64
kern.random.harvest.mask_symbolic:
[UMA],[FS_ATIME],SWI,INTERRUPT,NET_NG,NET_ETHER,NET_TUN,MOUSE,KEYBOARD,ATTACH,CACHED
kern.random.harvest.mask_bin: 00111111111
kern.random.harvest.mask: 511
kern.random.random_sources:

The boot time messages reported by dmesg show only this...

...
random: entropy device external interface
...
bcmrng0: <BCM2708/2835 random number generator> mem 0x104000-0x10400f on
simplebus0
...
random: unblocking device.
