Here's why I doubt there is a driver.
It's been that long and you didn't find it. Intel did not publish the source for us to play with either.
It's the usual card I use when I don't want to change the power supply.
That's 35 bucks to my door step and has all the usual video connections for a PCIe SLOT.

About 40 bucks.
