I've used a Matrox M9140 LP PCIe x16 card which provides four monitor
connections successfully under Fedora 12 and 14, but I had to use the
proprietary Matrox driver.

However, if you can find a PCIe x1 card that provides one monitor
connection, I don't see why it wouldn't work unless your power supply
isn't big enough to run it.
