cpu/motherboard swap with 9.0

It's time pull out my old 1.2 GHz T-bird and replace it with an Athlon 64 3200. Of course, this means a mobo swap as well. Can anyone here give me the details on the most painless way to do this upgrade in a dual-boot SuSE9.0Pro/WinXP box? I've got some good info on how to take care of the Windows side of the upgrade, so I don't think I need any help there. It's only the linux side that I'm worried about at the moment. TIA, Pete
