I use ifile, not bogofilter, but the two packages seem to be similar
in nature.  Yes, I get some false positives with ifile.  It's also not
like I didn't have a big pile of spam sitting around before I started
using ifile (I hand-sorted it into its own group); if nothing else,
you can set up a Hotmail account and wait for a couple of weeks.  :-)

You're using

> User-Agent: Gnus/5.090014 (Oort Gnus v0.14) Emacs/21.2 (powerpc-apple-darwin)

so you can just use the functions in spam.el.  My .gnus file has

(setq
      gnus-spam-newsgroup-contents
      '(("nnml:mail.misc.spam" gnus-group-spam-classification-spam)
	("nnml:.*" gnus-group-spam-classification-ham))
      gnus-spam-process-newsgroups
      '(("nnml:.*" (gnus-group-spam-exit-processor-ifile
		    gnus-group-ham-exit-processor-ifile)))
      gnus-spam-process-destinations
      '(("nnml:.*" "nnml:mail.misc.spam"))
      spam-junk-mailgroups '("mail.misc.spam")
      spam-split-group "mail.misc.spam"
      spam-use-ifile t
)

and I call (: spam-split) in nnmail-split-fancy.  I think all of these
should Just Work for you if you change group names appropriately and
substitute bogofilter for ifile.
