First foreseeable requirement would come from my side.
IBM's cell blades QS21/QS22 also support AEM/PEX.
On Power we don't have DMI information, but a slof device tree.

One could also add the open firmware path to the ipmi device.
But to avoid autoloading on other slof based machines with ipmi one would have to add compatible attributes for each machine.

So autoloading based on available ipmi sensors would be much better.
