Yes, I'm using it in a standard ASUS desktop motheroard.

I'm not entirely sure - the compatability list for the 3ware 9550
doesn't mention any 32-bit PCI motherboards at all, but the 9500 one
does.  Most (if not all) of the RAID controllers I've dealt with at work
will do 64-bit or 32-bit.  It may be that with PCI-X and PCI-e coming in
on most server boards, they're dropping backward compatability now - I
can't find any definitive guide that says they're compatible, and the
slot shapes would suggest that they might not be.

It's certainly a supported feature of the 9500 series and below - you
can check their compatability list.  If you're after the 9550 then I'd
drop them (or their local supplier) a mail about it - I got a very quick
response back when I enquired about their battery backup units a while
back.

HTH,
