Yay!

+1

Before X starts? I'd imagine a situation where someone insert a new 
display or that fancy usb video cards while the X is running. So in this 
case a hook inside the server is also needed.

Yes, this is what I initially thought as well. So I started nuking int10 
module inside the server and transformed in a library (which differs 
from mjg56's version which is not updated and synchronized with last 
xorg modifications). Maybe we could link it against the libpciaccess to 
do the POST/setup. I don't know, you can say it better.

     http://cgit.freedesktop.org/~vignatti/libx86/

(The X server side modification to use this library is trivial. Just 
link it against the library and git-rm hw/xfree/int10 basically)
