Been there, done that, got the T-shirt. This is not really correct.
KGI emulates the console switching procedure of standard Linux kernel if
no fully-fledged driver is loaded. Console switching events get sent
through to applications also in raw mode (as in raw mode cooked events
get filtered by the KGI-tty driver, and only raw events are handed on, just
the oposite to cooked mode). This is binary compatible with all
applications using this scheme, the only annoying 'feature' being
that <ALT>-<Fxx> works too for switching consoles from X, and thus takes
these combinations from applications. One should use <CTRL>-<ALT>-<Fxx>
on the console just as X does, but this requires changing all the keymaps
and documentation...

On another note, I think you should definately not change the semantics of
the console switching behaviour. This is used by other operating systems too,
so if you break this, you will make Linux incompatible with quite some
applications. (See the VT-switch handling code in the X server, as a reference).
