For the 12 head display this is true. We had to use Matrox cards as they didn't require softbooting which is not possible on higher PCI buses on the Netfinity due to a brain dead architecture of the Intel chipset used in this box. For the common case where one just wants to run 2 or 3 heads on a standard PC one can use pretty much any graphics card available. I'm frequently testing configurations with a mix of *different* graphics cards including ancient ISA boards. There weren't many setups I couldn't get to work. The only problem I do recall was when I was trying to get a dual MGA G200 card (with two G200 chips) to work with a G450 dual head card. This configuration didn't work appearantly due to limitations in the binary only HAL library provided by Matrox. Therefore I really don't understand the big fuzz about getting multihead to work!
