> There are very few 1-package motherboards out there that have 'server' features like ECC memory, serial or network consoles, etc
Even most desktop motherboards support ECC these days and have serial port pin headers at the very least. All Intel server motherboards (and probably HP and IBM too) come with BMC and an optional IP KVM addon.

serial port pin headers are not he same thing as having a serial console.
how many of these Intel server motherboards are single socket?
I've purchased single-package systems from HP, IBM, Sun and other tier-1 vendors. In every case the system that I received had a multi-package motherboard with only one package installed in it.
In that situation, the most cost-effective way to get compute capability is to go ahead and fully populate the motherboard. Even if that (usually second) package isn't as efficient as it would have been in a separate system (with no contention for RAM bandwidth, etc) it's still the best thing to do because the marginal cost of adding it to an existing system is so small.

See R1304BTLSHBN for example (S1200BTL), it has a single-socket ATX motherboard in a 1RU chassis, ECC memory and an optional IP KVM addon.
