Yes.

I guess the kernel isn't stripped of all symbols, only the debugging
ones, see this snippet from the Makefile:
${KERNEL}: ${FULLKERNEL}
objcopy --strip-debug ${FULLKERNEL} ${KERNEL}
.endif
naddy@bigeye[~] ll /kernel /sys/compile/BIGEYE/kernel*
-r-xr-xr-x 1 root wheel 1986324 Feb 7 01:57 /kernel
-rwxr-xr-x 1 root wheel 1986324 Feb 7 01:57 /sys/compile/BIGEYE/kernel
-rwxr-xr-x 1 root wheel 7471207 Feb 7 01:56 /sys/compile/BIGEYE/kernel.debug
This is simply the result of
# config -g -r BIGEYE
# cd /sys/compile/BIGEYE
# make depend && make -j2
# make install
