i don't think you have to play with the registry to do this.. just edit the manila file to point to "threaded View" instead of peopleMessaging. problem is, there are so many manila files i dunno which one it is..

if you look in this attached file which was the work-around for wm 6.1/sense 2.1 you'll see it directs to "ThreadedViewPage" parameter.. i think the new file in 2.5 is called 486d3b1a_manila which probably is the file that has to be edited in a similar way. for all i know "ThreadedViewPage" parms could have been removed/rename to something else in 2.5.

oh well, who ever wants to take a stab at it..
