Re: integrated cookies failing on trunk
This was my fault apparently.
Somehow the pluggable.php within bbpress was built 1074 when it absolutely needs 1075 to have the new wp_salt function.
So future note for integration to others:
to use the new WordPress 2.4/2.5 trunk
you MUST use bbpress build 1075
build 1074 and build 1076 will not integrate properly as is
