Yes, MS Office is Corporate standard even for Open Source developers -
It doesn't help to have unwieldy and difficult URL's for trivial things
either... :-(

Rev F is the version that has SVM, which is also the version of
processor that has DDR2 interface. The new DRAM interface means a new
sockets, AM2 being the "desktop" version of socket. There's also a
Socket S1 which is for mobile platforms and a Socket F that is for
servers, i.e. Opteron models of the processor. [AM2 was originally
called M2, but that's a trademark of some other company, so we had to
change it...]

The key is really Rev F, sockets are just a side-effect of the revision,
if you see what I mean. 

There is, listed on the "Compare processors" page, Sempron with Socket
AM2 (i.e. DDR2) - These could, in theory, have Virtualization, since
they would be of the same generation of processor core as the more
expensive models - but I couldn't find any detailed specs. The Anandtech
site indicates that Sempron isn't going to support virtualization
hardware, so the safer guess is that it's not supported on this product.
