I would expect so. Lots of people use more than two displays. I don't know
that any single addin cards exist with more than two ports where one is not
composite or SVHS, so most must be using more than one addin card. I wouldn't
expect all using more than two to be using motherboards with more than one
PCIe slot designed for video cards.
Do note that ATI is supported by KMS drivers (as are Intel and NVidia), while
MGA is not. Combining ATI with MGA could produce a compounding problem.
Also, there might be some BIOS setting you can change to enable simultanous
use of your onboard video with an addin card. Check your motherboard
specifications to find out.
