I ran into exactly the same problem on an older Dell motherboard
with a built in ATI video. I spend a *lot* of time trying to
get it to init both the onboard video and an external
one... with zero luck.

The eventual solution was to install a second video card.

(It only needed to do 1024x768 on a pair of 15" LCD screens for
a Point Of Sale system; hence the box now has a couple of "junk
box" video cards that respectively have 4M and 8M of video RAM.
The cost wasn't much in cash... just a lot of frustration in
the process.)
