I've ported the Dallas 1-wire library using the 2106 timers.  See 
http://www.aeolusdevelopment.com/Articles/download.html

I need to do a little maintenance on it to bring it into line with the 
latest version of the newlib-lpc timing (it uses the previous version) but 
that's minor calling differences.
