You have it backwards. Crossfire works on pretty much any motherboard with multiple PCIe slots, provided they have sufficient bandwidth between them. SLI requires the motherboard manufacturer to purchase a license from Nvidia to support SLI on the board.
If I'm not mistaken, Intel's X58 board was the first Intel-made board to support SLI, and I don't think anyone made a P45 board supporting it.
