I've upgraded a few machines from 4.x to 5.x without any problems.  I  
followed the instructions in /usr/src/UPDATING.  cvsup your machine  
to RELENG_5_4 and look towards the end of /usr/src/UPDATING for  
instructions.  There are a few important steps that I haven't seen  
documented elsewhere.

Good luck,
