PAE is a horrible hack, and even if you figured out why it won't compile 
(probably an incompatable driver in your kernel) it's slow.  That particular 
CPU will run FreeBSD/amd64 just fine.  (I happen to have one)  The drawbacks 
to FreeBSD/amd64 are mainly in the desktop arena.  If this is a server I'd go 
for it.
