Hi, sorry if my earlier reply was a bit redundant with Ali's here. It ended up in my spam filter somehow. Anyway, one nice thing about x86 systems is they all have the same core platform that's been the same forever, and it's well understood and documented to the point that I could find some useful information on wikipedia. For most of the basics there was really only one choice, although if we get into the fancy stuff later we'll probably need to pick a particular chipset to emulate. I'm assuming you're going to want to run Linux? You could check to see what hardware it supports. That will enable one important workload, probably be pretty representative of your average real Power system, and will likely have documentation.
