Okay this is a simpler approach so I'll use it. One thing I'll add is
to also add a synth_name variable to speakup. When setting dev we also
set synth_name so that dev override doesn't happen for some other
synth module that gets accidentally loaded between us setting
speakup's dev and us loading the synth driver module. Highly unlikely
but can potentially brick a synth, e.g. during testing.

Thanks,
