Which mirror, and which distribution (sid/sarge) did you choose
to download from?

Not really, I suspect some mismatch in the package propagation to

Yes, but changing "where the root files are looked for" is not really
the right way.  Just use the debian-installer tree to build
yourself an image which includes all the udebs which are
currently spread between boot and root.

I suspect the device spec is not quite correct (the /dev directly in the
installer is not 100% compatible with the normal /dev structure).

Sure, there should be.  At least the scripts on the boot.img
does load the root.img files from floppy.

I dont quite get this, or it feels too hackish to me.  The right
way to do this is to let apt-get install brltty into the
installed system, everything else leads to a mess.  You really shouldn't
untar arbitrary files onto a freshly installed system, especially not if
they happen to have the same names as a package would provide.
This is OKish for a short term solution, but not really useful if we
want to see real accessibility support in Debian.
