I think something did break back at the start of the year that caused /boot.config contents to render the system completely unbootable. At least that is what happened to me on RELENG_8: http://lists.freebsd.org/pipermail/freebsd-stable/2013-January/071579.html Bruce A. Mah reports later in the same thread that his happened to him on 8.3-RELEASE. I don't know if this was fixed.
