However I need to disappoint you a little, this is not a PR, but a general question. Can you please email the freebsd-bugs and/or freebsd-current mailinglist(s) (findable via http://lists.freebsd.org/mailman/listinfo/) and get helped that way? (People will probably help you sooner that way as well). Thanks and Cheers! REmko
