I'd like vc hooks in the kernel, and a user-space way to use them.
keep the VC system the way it is, but allow a user process to modify
the kernel vc table. And to those who mentioned using screen on
a single local console... bleaguh! alt-f1 through ctl-leftalt-shift f12
is much nicer. BUT:
if there were hooks in the kernel for it, then a dumb-terminal on
the serial port could be sending _IT'S_ alt-f1 sequence, and pulling
a vc that way. (perhaps like screen does, ttyq etc.)

besides, X needs the vc's as is, and I'm sure that everyone would
_LOVE_ to have to recompile their x server to do the switching itself.
So, internal stays as is, but how about: select_vc(), etc. that
can be used as well as the internal alt-fkey hooks.

just my 2c
