Documentation on support for platforms not x86 is unclear

The following email was recieved from a customer after it was mentioned to him that we do not oficially support Confluence when run on SPARC:

I have to say that I was not aware about the SPARC exclusion, something that will prove an issue here since we have no Intel based hardware. The documentation is not really clear - for example, here, it is not mentioned, and here it is rather ambiguous (I initially read the line as Mac OSX on x86 only, not all of the preceding OS on x86 only).
