Not sure which versions you’re running, but cookies are compatible in bbPress 0.9.0.2 and WordPress 2.5.1. They changed the cookie hash method. If the changeset is equivalent to 2.5.1 (my /tags/2.5.1 WordPress installation is changeset 7835) then the cookies should work, so long as you’re using bbPress 0.9.0.2.

What bbPress version are you using?
