VMware Hot-Add Memory/CPU Support

I've been asked to take a look into the Hot-Add Memory and CPU features which are available with vSphere 4. The concept seems pretty useful and straight forward, but what isn't is the list of Operating Systems that support these features. There doesn't seem to be a definitive list. Either that, or I should have gone to Specsavers?

I've had a look around and I can find two KB articles from VMware: Here, and Here which talk about using Hot-Add on Linux OS's. Another VMware document focused on Microsoft: VMware Guest/Host OS Compatibility Guide There is Jason Boche's great article which he researched and tested himself, And Daniel Eason's summary on Hot-Add.

From these different articles I have taken all of the information and produced the following table which in theory should be all of the OS's which support VMware Hot-Add Memory/CPU.
