I can provide a little insight here, as we hit the same issue when
AIX went towards 64bit. There are a surprising (at least to us at the 
time)
number of tools and applications that read utmp/wtmp. Some of them were
user apps that really had no overriding reason, but all the same we took 
some
dings during the change. Not that the change can be avoided, but it is 
probably
a Good Thing to advertise this about a bit before doing it.
