No.  We discussed this several years ago, and we concluded that it won't
work.  It's pretty much infeasible to use the tty devices (/dev/ttyS*)
from kernel space.  That discussion might be available in the list
archives.  I've been told that the solution to our serial problems in
Speakup is to write a tty line discipline.  I don't really understand
how to do it.
