Sometimes I've been thinking about this as more and more hardware don't
ship with RS232 anymore.  Is there a relatively common BIOS interface
which would allow, even if non-efficiently, to use a USB port as a
serial device without too much code?  If so, possibly that a special
usb-serial bootblock could be using that sometime in the future?

If there is no BIOS common interface, I can see it's a problem because
of all the driver code that'd be needed at boot time...
