It looks like isa/sio.c still won't allow you to set a port as both
a low-level console and the gdb port.  I could not get remote gdb
to work correctly after the sio probe without designating the port
for low-level console I/O.  Now that I've done that, I can't debug
at 115200 any more.  38400 seems to work for me, but that is with
only minimal testing.  Who broke remote debugging in sio?  This
is a critical tool we can't afford to have broken... 8-(
