You've lost me. I use max and there is practically no difference between its bevel and the version currently implemented in maya 2012. Is there some feature you could describe that you are looking for?
BPT I believe stopped working for maya somewhere around version 8.5 as most of it's features were rolled into maya 2010.
Can you possoibly toss up some screen shots to show the issues youare describing with the triangles???
