The difficult bits rarely have anything to do with compilers and such
(especially given that most of the code has been through a 64-bit port to
the alpha).  The system-mode pieces of IA-64/Merced were not public until
recently; I noticed the full document set just became available on the intel
web site this week. There's also the Linux port that was posted to the web
in the past week or two; that should show what's needed for a FreeBSD port.

Of course, as was mentioned before, without hardware or a simulator it's
pretty pointless to put much effort into something like this.
