The default devices are *not* included by in the file created by 
-writeconfig.  So I tend to thing -readconfig should not automagically 
turn on -nodefaults to avoid unpleasent surprises for users.

Devices created via -readconfig are treated like devices created via 
[device] sections in the config file.  So it doesn't matter whenever you 
configure your isa-serial device via command line or config file, in any 
case it will make qemu not create the default serial port.
