Normal serial ports are dumb animals with no backchannel.  I'd expect
things to work that way if xen just emulated a serial port and you had
to boot with console=/dev/ttyS0, but when you've got a proper console
driver, it would be really nice if it did the right thing ;)

I have no idea how things work on the xen/xl side of things but I
probably could work up a patch for the hvc driver side.
