Intel D875PBZ support?

Hi, I have a new machine based on the Intel D875PBZ motherboard, so I'm wondering whether the Intel 875 chipset is supported? The machine has things like Serial ATA disks, Gigabit LAN, USB cordless keyboard/mouse, ATI Radeon 9000 graphics card. So I'm also interested in any pointers regarding those, if they're not automatically supported. Thanks, Dave
