ppp(4) or sppp(4)?  Looking at the patch, it seems to be sppp(4),  
which is (completely?) seperate from ppp(4), AFAIK.

Also, ppp(8), Brian Somers userland PPP implementation, is not  
affected; a useful bit of information for people who are not as  
familiar with the multitude of PPP implementations in FreeBSD.
