If your CPUs don't support LM (long mode, aka amd64), then booting an amd64 image wont get very far. Judging from the ubuntu message, your CPUs dont. If you have installed/booted FreeBSD, you can find out what your CPU supports by looking at the Features mentioned in dmesg: > $ grep Features /var/run/dmesg.boot Features=0xbfebfbff Features2=0xe3fd AMD Features=0x20100000 AMD Features2=0x1 Iif your CPU supported amd64, it would be mentioned in AMD Features (as LM).
