I had some problems when I upgraded to current about 2 weeks ago - my rp-pppoe stopped working as well. I ended up reverting to a saved backup. It looked like a device problem so I re-did the install and made sure that the udev update (including the /etc/rc.d/rc.udev script) was applied correctly and it's working fine now.
If you haven't made any changes I don't know what could have caused it though...
