Sure, it's possible and actually not hard to do.  Just make sure that the 
driver of your primary card is fbdev, and the secondary X11.  X happens to do 
a fine job of initializing non-primary cards whereas fbdev is mostly 
restricted to cards initialized by the firmware.

Note: You wont' be able to see both displays simultaneously, switching from 
one blanks the other.   If you do want multi-seat, see the Ruby project of 
linuxconsole.

As for sensible, that's up to you :-)
