Re: keyboard mux driver (straw man proposal & code)

replying to myself :)

also bcc to folks who might be interested (mostly from vkbd(4) discussion).

i have changed the proposed kbdmux code a bit. basically auxiliary 
device interface is gone. there can only be one kbdmux. it is no longer 
required to keep kbdmux control device open. so, right now its pretty 
much pure keyboard driver. i have also updated test program (works for 
me in console mode).

http://www.geocities.com/m_evmenkin/kbdmux-1.tar.gz (~6K)

the code also on freefall in my home directory 
(emax_at_freefall:kbdmux-1.tar.gz).

thanks,
max
