[BRLTTY] Activation of Speech Dispatcher under squeeze

[Samuel Thibault]

BTW, the whole pulseaudio thing really doesn't make sense at all for
brltty: support for multiseat on the linux console has always been quite
broken and will most probably never be really implemented.  That is why
pulseaudio will really have a very hard time to try to convince brltty
people to implement a very tricky way that will never actually provide
any benefit, since there will always just be one seat.

For gnome screen readers the matter is very different of course.
