Needs lot of work.  Current CVS support one VT per all fb layer.

I don't know. X do not ask for VT but /dev/ttyX /dev/input/mouseX.
You can analyze gpm.

Not so deeply in XF86's. You can run multiple independ X without kernel
patch.

Under Linux we have not common sound solution. Any application use
different sound layer. I patch /usr/bin/startkde. Now this script
push into ~/.kde/share/config/kcmartsrc with right content.
User can run apps with aRTs support with his sound card.
This will not work for other desktop manager and games.
I have two sound cards in the box.
