I don't know why you would want such a high number however,
if you're serious about this first get the full souces I would suggest
CVSUP to make sure everthing is up to date including the ports collection.

 - Install your fresh system, including all the sources.
 - Edit the value of UT_NAMESIZE in /usr/src/include/utmp.h to 64 (or 
   whatever you want)
 - Edit the value of MAXLOGNAME in /usr/src/sys/sys/param.h to one
   greater than the value you gave UT_NAMESIZE (eg. 65)


Remake the world and your kernel.  Note that there are a lot of ports 
that use the UT_NAMESIZE parameter, eg. the POP server.  You *must* 
rebuild them on this machine for them to work properly. (ie. you cannot 
install packages, or ports that were built on another system).
