I built the kernel using 'make buildkernel' using a kernconf derived 
from GENERIC, only difference is some 'device' entries added and 
removed. I did keep a backup of the old kernel, so I ran ctfdump -S on 
both of them:

old: total number of struct members      = 38700
new: total number of struct members      = 528

So there's definitely something to this. If all else fails, I'll remove 
make.conf / src.conf and build GENERIC to see if I can get a baseline 
setup that works.
