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.

Yes the 64bit support of the Intel CPUs are well supported, I use a
Intel Pentium 4 640 and 64bit compiled system (Gentoo 2005)
I have no problems everything is working nearly perfect better as my
AMD64 system.

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

Cheep and good performance.
