You may do it depending on you xserver module. Have a look at the
xfree86.org pages. With a neomagic chipset, you just need to put (but one
video card = the same display on both of course!):
Section "Device"
Option     "intern_disp"
Option     "extern_disp"


If you have another chipset, do look into the man pages for your server
(for the neomagic, it is mentionned in the XFree3 pages but not in the
XFree4 ones though it works under both.
