I don't have any luck reproducing the behaviour you describe.

Built todays git master with
 
  ./configure --target-list=x86_64-softmmu,ppc-softmmu --disable-gtk

then ./ppc-softmmu/qemu-system-ppc -sdl


pops up the main SDL window with primary VGA showing firmware output.

I can then Ctrl-Alt-2 to popup monitor console, and Ctrl-Alt-3/4 to
popup serial & parallel console.  The serial console has  some input
in it, and the monitor console responds normally without affecting
any other windows.

Can you provide further information about your host architecture, and
your host OS distro, and whether you gave any other special options
to configure or qemu-system-ppc

The only annoyance is that the serial & parallel console windows get
placed directly on top of the monitor console window instead of letting
the window manager place them in a sensible place.

Daniel
