Didn't I just answer that question?

On Linux: no.

There have been a couple projects that attempted to allow
drivers to be written in user-space.

  http://www.circlemud.org/~jelson/software/fusd/
  http://www.gelato.unsw.edu.au/IA64wiki/UserLevelDrivers  

However, AFAICT, both of these projects are defunct and neither
provided an interface to the TTY layer.  Without a tty-layer
interface, you would have to duplicate the entire tty layer in
your user-space driver driver as well.
