Thanks to Scott Spencer, Michael Imrick, K. Rossman, Martin Presslaber, and Dilip Madhavan. Short answer: Yes, the boards are absolutely swappable between Sun Fire models, hence their name, "uni-board." :-) All memory is supported, but CPU mixing is only supported with CPUs at 900MHz or faster. Firmware must match. The known caveats are: * CPUs don't have to be the same speed, but the lowest speed for mixing compatibility is 900 MHz. * The firmware revs of all uni-boards on a single machine must match. The board being added can be flashed from any other active board on the machine. * Memory of all models is supported, but the slowest memory module will drag all others down to its speed in a given domain. It is also widely suspected that only Sun SSEs are allowed to perform this operation per any support contract offered by Sun, i.e., if you do the swap yourself, you void the support contract. I've never seen any Sun Fire uni-board work done by anyone but a Sun SSE, and they keep detailed records of each machine.
