Unless 16550A's are somehow not backwards compatable, all this solution
suggests (besides the fact that people should check for serial
misconfiguration) is that something about serial handling got slowed
down or delayed severely...especially if input from a serial mouse was
dropped. Linux really ought to be able to handle 1200 bps without a
buffering UART, at least on a reasonably fast (20+ MHz) 386SX...
