This initialization may be a requirement, that don't mean
it is going to happen. Someone might crack your machine
and burn a new bios for you without RAM initialization.
Then they physically break in and take the box when
they believe there's something worth stealing in it.
(I.e. something interesting is on the disk, and the
decryption keys is in memory.)

Non-erasable bioses can of course be replaced too.
This can be done "live", as modern os'es don't use
the bios much after booting anyway.
