John,

The x86_64 built Scientific Linux kernel should at least be binary
compatible with the Xeon-64 processor. However, the chipset support for
this processor is most likely not supported. It may be a version or two
of the redhat enterprise kernel before Redhat and or Intel gets around
to incorporating the needed changes for PCI Express, and the like that
the new chipsets supporting this processor use.

If you look in the redhat source build spec's you will notice that they
have the option turned on to support this processor. I did not however
notice any additional code for the new chipsets last time I looked at
the build specs a month ago.

So yes and no, the processor may be supported but I think you may have
to wait awhile before you get a linux distro that runs on it because of
the chipset support.

You could always try bleeding edge Fedora Core 3 test 1 though. It's
possible that these changes have already started to make their way into
the 2.6.7 kernel.

I hope this helps,
