Yes, SMP is supported.

You can probably use hardware raid cards.  You might be able to use your DPT 
card, but I'm not sure.  There is also software RAID available via gmirror, 
gstripe, etc.  The best bet for your card is to just boot an install CD and 
look in the dmesg to see if it finds your disks.

You can install whichever versions of postgresql and apache that you wish 
using the ports collection.

I don't think everything is chroot'd by default, but you can certainly run 
processes in chroots (or better yet, jails).

FreeBSD doesn't support the floppy drive on any of the sparc64 machines AFAIK.
