You know... we already have a command-line parser in the real-mode part
of the boot code, and it already extracts the "quiet" option: we should
be able to do this by passing a bit in "loadflags" (bit 5 suggested.)
This would have the additional benefit of making it really easy for
hypervisors that don't support writing to the screen at all to disable
those messages.
What do you think?
