-Wuninitialized has helped me catch a number of bugs on the pmax - I
can't remember how many were in MI code vs. MD code.  From Jason
earlier in this thread:

Do we know in this particular case whether or not it was a false
positive?  Until INET6, pmax kernels were building happily for a
couple of months with this option.

FWIW, sparc64 seems to be the only other port that uses -Wuninitialized...
