I would be happy to help/test/whatever also. I have an 8 core Intel workstation currently running CentOS 5.5 (w/ Plus kernel). I also have a spare hot-swap system drive to install and test version 6 on, or I can run it in a virtual machine under 5.5. FWIW, Scientific Linux 6 is currently available in beta form. If I can't get CentOS 6 at least in a beta form pdq, then I may be switching to SL instead. Since my wife is a physicist on the computing division staff at FermiLab, at least I know who to gripe at when problems arise! Of course, that doesn't mean she'll listen/respond to them... :-)
