I think that we can imply from the lack of response on this subject that 4.x
is not really still supported, since just about all of the new motherboards
for Intel processors from leaders Dell and Supermicro are based on the 
7520. So, ironically, in order to use the newer, faster processors with 
FreeBSD, you have to use the newer, slower version of the O/S. Yikes!
