Oh, absolutely. The final keyboard/terminal server should handle scan codes
and not mach pseudo key codes, which lack a zillion features anyway.
To see how the responsibilities are to be distributed, take a look at Kalles
colortext, which sits between Mach and the term server. This is the program
that should get the scan codes instead the Mach codes, and this is the
program where virtual consoles would be implemented. (It makes sense to have
both in one server. What you do with multikeyboards and multiscreens is not
too important right now).
See http://stekt.oulu.fi/~tosi/gnu/hurd#toc_colortext
for the source code.
Thanks for pointing this out,
Marcus
