Default FS Layout Too Small?

I believe this is because with 7 and beyond a "make installkernel"
will install the symbols into /boot/kernel if the kernel is compiled
with debug support. With 6.x and earlier it would keep them in the
/usr/obj hierarchy but not deposit them into /boot/kernel.

Not saying one is better than the other (although it is nice to have
the symbols in an easy-to-find directory when needed), but that would
explain why your average kernel now needs 3-4x the space if you've
enabled kernel debugging.
