If the only part of this that's bogus is the 'ttyS2' hard-coding, does that
mean the kernel does have the capability to send console output to multiple
TTYs? I've never tried this before, but had noticed this bit of code; if it
works, we could just have --dev beagle set both consoles on a transitional
basis, right?
