I was able to get legacy networking running on amd64 with something along the lines of config -e -o /bsd /bsd disable acpi disable mpbios disable ioapic however, amd64 on hyperv was very unstable for me. I would simply freeze after a few minutes. The commands above also seems to increase i386 performance on hyperv, as the cost of losing MP.
