I have been running with the 1.1 drivers and an old EtherPort card for a couple
of months now.  While everything works, I can also suffer kernal crashes/system
lockups whenever I attempt heavy usage that uses lots of memory.  When I do get
a panic message, it always points to a tcp/ip task as the bad guy.  I am doing
all of my appletalk stuff over the localtalk wire.  

The bottom line is that the 1.1 drivers will get your running, but will make
your system flakey.  If you aren't a heavy memory user, it might work fine.
Personally, I am trying to get a different ethernet card.
