Home (which is the version I already have) only supports one processor -but will support multi core single processors
Thanks for getting that right for once. There are SOOOO many people who think that Home won't support their Core 2 Duo processors.
The retail XP Home SP2 Upgrade CD I used for my Boot Camp install worked just fine with my iMac, and I've also recently had the "pleasure" of downgrading a number of Dell Vista Conroe boxes to XPSP2 with the Dell install CD and had no SATA problems, except for the one case where a piece of software I need only installs properly on SP1, so we had to install SP1 first, the app and upgrade to SP2.
Is it actually legal to run OEM? (I mean a brand new one, not one that came with an old computer.)
Read the Systems Builders License and decide for yourself. The previous version seemed OK, but the latest seems to have a bit more restrictions. I read it that it's acceptable
if you can support yourself,
and you don't redistribute the license. i.e. remove it if you sell the box. Most of the OEM restrictions are tied to redistribution (when you redistribute you must preinstall and support the install you distributed).
