need a video driver

I got a card that came out of an intergraphic server. It is a dual pci card the top card has a cirrus logic chip 5440. The bottom half of the card is a full sized card, with two large fans and removable sram memory.The processors on the bottom card have heat syncs that are unremovable. The only model info is as follows:csmt2590a. Anyone ever see one of these? By the way I did try the generic cirrus logic driver it works in 256 color mode only. I think the bottom of the card may be a geometry generator.
