Ok, on the kernel boot, please send me:
sysctl kern.bootfile kern.module_path
ls /boot/<dir of kernel from kern.bootfile>

Make sure that you're current kernel is built to include modules.  We
no longer will load the default kernel's modules for other kernels.  So
if you boot kernel.test (or other kernel) that does not have pf.ko, you
can't load pf.ko anymore.

Note, I just tried to kldload pf on my system with the above change,
and at first it failed just like your case, but that was because I was
on a kernel w/o any kernel modules.  When I rebooted back to the
regular kernel, kldload pf worked perfectly... the unload didn't go
so well:
kldlopeabody# kldload pf
peabody# kldunload pf
panic: mutex if_clone loc
