There are only issues with CPUFREQ/speedstep and some ACPI related things on Intel 955X chipset I have. So I use a ASUS P5WD2-Premium. The Pentium D will reach me in few days so I only guess and I think the kernel know how to handle Physical Cores and SMT/HT Processors. > > The specs indicate that 64 bit is supported, is there any actualy > Linux support for the Intel 64 bit stuff in gcc and the kernel?

For GCC 3.4.x or 4.0.x you only need the compile switch -march=nocona as the name of the XEON..but its the same piece of technologie > The price is lower than a dual Xeon setup if you have an application > which needs SMP, and initial power values make it look like a lower > power solution overall. Cheep and good performance. Greets Best regards Michael
