No change even after a fresh buildworld (using RELENG_6):

cvsup /etc/supfile-src && rm -r /usr/obj/* && cd /usr/src && make make && 
make clean && make cleandir && make cleandir && make buildworld && make 
buildkernel && make installkernel && make installworld && mergemaster

I don't mind leaving the option in the kernel, but it does seem like a 
strange bug.  Let me know if anyone has any other ideas.  Thanks,
