NetBSD seems to be interested in just about everything. I think
the early support for PCMCIA and USB proves that NetBSD isn't just for
old hardware. Not to mention the fact that NetBSD ran on the iMac
before Apple could get Unix running on it. I also think that since
NetBSD already runs on several 64 bit processors and has extremely
clean code, it shouldn't take much to make it run on the IA64. So, I
would expect it to be one of the early adopters. I also expect that
both FreeBSD and OpenBSD will be there as soon as they can as well,
since it will be necessary in order to remain a force in the PC server
market (especially FreeBSD, which is pretty much strictly a PC OS; not
counting their Alpha effort).

Maybe, but I'm sure they have other stuff in the works (Intel as
well, of course).

None. It's still in the design stage, and is supposed to hit the
streets about a year after the IA64. It is supposed to be a true 64 bit
architecture based on the ix86. This should gain a lot of points since
it will be easy to port 32 bit ix86 stuff to it. However, I have to say,
the ix86 is one of the grossest chips that I've programmed (6502, S/370,
ix86, and I can read 680x0 but haven't written any). I don't do a lot of
assembly language programming anymore.
