geli: pass user password from loader?

[Lev Serebryakov]

Hello, Freebsd-geom.

 I've installed 10-RELEASE on laptop with geli + ZFS, and now it is
annoying, that geli password prompt is overwritten by next kernel messages
(about USB devices) and prompt is very plain and dull :)

 But we have forth in our loader, so nice screen could be written with some
message like "This Laptop belongs to Lev Serebryakov <phone> <email>, Please
enter master password to boot:" and input line in nice frame could be
programmed (in addition to our standard boot menu).

 But is it possible to pass password string from loader to geom_eli? "man
geli" doesn't show such possibility :(
