Indeed it is.  The command on IOS-based switches is "spanning-tree
portfast", and on CatOS switches, "set spantree portfast x/y", where x
is the blade #, and y is the port # on that blade.

Yep, I can see that happening.  Remember that, with IPX/SPX, the network
address is done by MAC address (not so with IPv4), and the addresses are
thus auto-assigned (no DHCP).  IPv6 "borrowed" this little trick and
thus doesn't need DHCP any more than IPX does.
