I quick google search shows that the Lindenhurst chipset, e.g. E7520, is for EM64T processors so the amd64 should work on your system. That said, unless you have a compelling reason to do so, the i386 port works fine too, and at _present_, some things are still easier to do with the i386 port, e.g. java and linux emulation.  

I have a similar system running xen with netbsd-3/i386 on dom0 and the domU's and so far no complaints. Someday, xen 3 will work with the amd64 port, in which case I'll make the switch.
