I have just verified that the development version of Emacs will start
up 8-bit transparent if the LC_CTYPE locale is indicating an 8-bit
character set.  So this will work out of the box with Emacs-21.4.

I am afraid that I have not been able to find the manual methods from
term/linux.el in the Emacs-21.3 manual, though I am pretty sure that
at one point of time, the above somewhat arcane way via set-input-mode
was described there.  Maybe the documentation changed faster than the
code.
