For any of you that have 64 bit AMD boxes you may want to try out this 64 bit remastered version of Knoppix. I don't have such hardware so I have no idea how well it works, but it's certainly a good idea. From the author's description it does have some limitations, but still seems worth a try.

Here's the link for those interested:
