Just got a new laptop (amd64 3200+ and 512 megs of RAM) and would love to push slackware onto it. However, slacks runs by default at 32-bit. Is there a slackware 10 installation/packages someone has precompiled for amd64 processors?

Is there a way I can do it manually?

Better yet, is it even going to make that big of a difference if I don't optimize to use the 64bit?
