3rd party kernel modules go in /boot/modules and /boot/kernel is for
FreeBSD only.

Yes, this drives me nuts too. For example the kqemu port gets
installed in /boot/kernel and highpoint's manuals tell you to install
drivers there too. The problem is that if you rebuild your kernel or
do a buildworld et. al. it will wipeout everything in /boot/kernel...
This is why we have /boot/modules, everything in here will survive a
kernel rebuild, buildworld, etc...

"module_path
Sets the list of directories which will be searched for modules named
in a load command or implicitly required by a dependency. The default
value for this variable is ``/boot/kernel;/boot/modules''."

" /boot/ programs and configuration files used during operating system

defaults/ default bootstrapping configuration files; see
loader.conf(5)
kernel/ pure kernel executable (the operating system loaded
into memory at boot time).
modules/ third-party loadable kernel modules; see kldstat(8)"
