Using your favourite news reader, subscribe to gmane.linux.ports.ppc.embedded newsgroup at server news.gmane.org, and get it to suck back all the messages it can (you'll get in the order of 11800 - back to about Feb 2002). Then use your news reader's search features - a decent one will allow regex searches, etc.
See www.gmane.org for more info on how it makes mailing lists available as newsgroups. Cheers, Ron
