This "feature" shouldn't be implemented in speakup but mainstream:
serial consoles would benefit from it too.  And the kernel actually
_already_ has support for something similar, it's called "early serial
support" (for supporting it before IRQs are set up), and could be reused
for this.

What is the difference between having a hardware synthesizer talking
and outputing plain text on the serial device? (from the point of view
of a kernel hacker that wants to quickly check that speakup still works
I mean, not from the point of view of someone actually working on

That doesn't permit do work on the serial support, which is one of the
key points of integrating speakup upstream.
