> Has anyone evaluated running FreeBSD with Intel's > x86-64 extensions (which appear to be a copy of AMD's?) It's much too soon for that. Just a few days ago at the IDF, Intel pointed at a box and claimed it had an x86-64 compatible chip in it. Noone was allowed to check it and nothing was demonstrated on it. Intel says it will be months before chips are available. Don't look for anyone other than major Intel distributors like Dell to even have prototype chips until summer. I have downloaded Intels manuals on the chip and it is identical to AMD64 with the addition of the Prescott New Instructions (mostly SSE3). There should be no reason why ia-32e (what Intel calls it) cannot run FreeBSD. Microsoft claims XP 64-bit Edition works on it. They probably ran it on the box that Intel had at IDF. Oh, there was ONE difference between AMD64 and ia-32e: the No Execute bit in AMD64 is not in ia-32e (yet). So if FreeBSD is using this bit, it will be ineffective on ia-32e based systems... unless Intel adds it between now and when the chip is actually available.
