Sounds like you didn't read the debian installation manual, or didn't
look at wiki.debian.org/accessibility. In the case of a USB braille
display, brltty detects it automatically. In the case of serial
displays, the debian installation manual describes how to pass the
appropriate options to brltty when starting the installer.

As far as speakup hardware synthesizers, they're also supported. You
need to press tab, space, and type speakup.synth=xxx at the boot
prompt, where xxx is speakup's designation for your synthesizer.

Yes, everything is together in one kernel, and I can assure you they
do all work together, brltty, hardware synthesizers, and all.

You'll need to be more specific.

You'll need to provide enough details to reproduce the problem. What
did you do to make it happen exactly.

Brltty isn't in the kernel, it is entirely in user space as far as I know.
