We'll probably use the most straightforward way:
a) trezor prints entropy A on a display (probably in hex format, this
step is triggered by sending a special flag in initialize message)
b) trezor receives entropy B from external source
c) trezor creates sha256(A + B) and uses that as a seed
d) trezor prints used seed on a display (probably in BIP39 format)
e) user can check on a trusted computer that everything was ok
(note that steps b-d are the same regardless of whether the special flag
was set)
