This would be really nice.

Alright.

Right.

It should already be attached to the first console. I never liked the
idea of mapping devices from one head to another. Fbdev does this and it
has it problems.

Hot pluggable devices will be fun to deal with. For a fully functional
console you want it to search for the one lacking that part and fill it
in.

Yep.
