The thing is that it would be sad to re-implement these drivers, as
getting hardware to make sure they work is hard.

That seems like a good way. The core of screen reading can be
implemented in GRUB and drivers be modules.

I know.  I didn't send the patch for inclusion, but for hpcoder to have
a look.  The story is that I met him at lsm and found he was interested
in implementing something so since I had already done some stuff it
could be a good thing for him to have a look at it.

Same reason: that wasn't code meant for inclusion, it wouldn't be
implemented this way, though for this precise driver there would be such
array, converting from the ISO 11548-1 encoding of braille dots into
VisioBraille's own encoding of braille dots.
