The original Core Duo (and Core Solo) processors were 32-bit only and never became very widespread. The later Core 2 series supports both 64-bit and 32-bit operation and became quite popular, and I am fairly certain that most of the people you say you have seen claiming to run FreeBSD with a Core Duo are actually using a Core 2 Duo. As for your own C2D E8400, well the 'C2D' is short for 'Core 2 Duo', so yes it should support amd64 just fine. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
