Nice -- didn't know that Intel now had a serious remote management offering. These AMD mobos do wake-on-LAN, and that's it. They don't even have serial BIOS.
To be honest, Intel's AMT is a bit of a PITA, but the Orange Boxes were assembled to have some resemblance to real racks of hardware. So remote out of band power control is essential.
There's something quite magical about using Juju and MAAS on the Orange Boxes and seeing the LEDs light up as you scale out a service (e.g. juju add-unit -n 5 nova-compute).
Every single Supermicro and Tyan board I've ever used. Also every Dell, HP, and Sun/Oracle server I've ever used (though those can be a bit more of a pain). Really, anything with a halfway-decent IPMI implementation.
The IPMI spec lets you send the entire console (BIOS through login boot cycle) out either the hardware serial port, or over a LAN for all those platforms.
