Welcome to the fun world of default devices.  We'd love to get rid of
them as they also cause other similar grief, but we can't if we want
maintain backward compatibility :(

I strongly suggest to simply use '-nodefaults' if default devices get
into your way.  Defining the serial line the way you want it using
'-serial $args' or '-device isa-serial,$args' will work (in that
specific case) too.

I don't feel like adding more band-aid to paper over the fundamental
issue.  Too much band-aid tends to cause other unwanted side effects.

cheers,
