Ran the update last night and just got my mini-network back up.
I'm connected to a cable modem on a DP550 via ethernet, then to an 800 iBook via AirPort and on to a PM8500 via ethernet. Seems several settings changed, found the culprit a little while ago - iBook thought it was connected via ethernet, not airport. Now the 8500 can see the web and is back to crunching SETI. No other problems noted yet.
