I was curious, so I looked a bit myself, and found this:

% ag ctrl-alt-f /usr/share/doc
/usr/share/doc/kbd-1.15.5-r1/html/kbd.FAQ-7.html
21:<P>By default, console switching is done using Alt-Fn or Ctrl-Alt-Fn.
22:Under <CODE>X</CODE> (or recent versions of <CODE>dosemu</CODE>), only 
Ctrl-Alt-Fn works.

/usr/share/doc/kbd-1.15.5-r1/html/kbd.FAQ-8.html
54:Console_n       Alt-Fn and Ctrl-Alt-Fn  (1 &lt;= n &lt;= 12)
82:Ctrl-Alt-Fn     Switch to VT n
115:Ctrl-Alt-Fn     Switch to VT n (from version 0.50; earlier Alt-Fn)

/usr/share/doc/kbd-1.15.5-r1/html/kbd.FAQ-13.html
28:While it is running one can use Ctrl-Alt-Fn to switch to VTn.

/usr/share/doc/kbd-1.15.5-r1/html/kbd.FAQ-9.html
41:However, Ctrl-Alt-Fn will work and you can go to another VT.

/usr/share/doc/libsdl-1.2.15-r9/html/docs.html
631:    The framebuffer console now uses CTRL-ALT-FN to switch virtual 
terminals, to avoid collisions with application key bindings.

(Online here: http://kbd-project.org/www.win.tue.nl/~aeb/linux/kbd/)

(For those who haven't heard of it: ag is from sys-apps/the_silver_searcher.)

From a cursory look, I couldn't find anything specific, other than that 
apparently AltGr+Fn is supposed to give you console n+12 (though apparently 
not from within X), but it didn't work for me, and I'm not in the mood to find 
out why.  Also, that FAQ looks... dated.  However, maybe it will help lead you 
to a solution?

Also, while I'm sure you've got a good reason for doing this, I'm really 
curious: why not use screen or tmux instead?  Especially if you're dealing 
with more than twelve terminals.
