This inspired my curiosity enough to try the boot-only image and see if it boots and runs at all, which it does perfectly! It turns out that "Intel(R) Xeon(R) CPU >>>> 5130 @ 2.00GHz (2002.99-MHz 686-class CPU)" can do the 64-bit thing (note the "5130" part) [*]. The time has come to say 32-bit only when meaning "not 64" :-) Goodbye, i386!
