It is strange, but there's a way to confirm it is gcc: with your world 
built without setting CPUTYPE (as you have it now), compile and install 
*JUST* the loader with CPUTYPE defined.  The steps to do this (the 
'grep' just shows that CPUTYPE is set):

# grep CPUTYPE /etc/make.conf
CPUTYPE?=p-m
# cd /usr/src/sys/boot/
# make depend && make && make install && make clean && make cleandepend

When I tried the same thing on my athlon-xp machine, the new loader 
worked.  So it is only when gcc is compiled with CPUTYPE set that there 
is a problem.  I now run 5.4 on the machine and no longer experience the 
issue, so who knows...
