Thanks for the report, but it looks like there is already a request to solve this problem by stabilizing broadcom-sta-5.60.246.6. You can add your observation about disappeared tarball to bug 350069, to add motivation for getting this stablized... *** This bug has been marked as a duplicate of bug 350069 ***
