I think that debug symbols are in another files (*.symbols)
FreeBSD 8.3-RELEASE amd64 GENERIC

-r-xr-xr-x 1 root wheel 12M May 8 2012 /boot/kernel/kernel
-r-xr-xr-x 1 root wheel 50M May 8 2012 /boot/kernel/kernel.symbols
So a kernel alone has 12MB, with debug symbols 62MB (12+50).
And all *.symbols files can be deleted (if more space on /boot is needed)
I don't know how it should be mentioned in FAQ.
