Theoretically it should work.  It's not necessary to overwrite your current
kernel.  You can do something like this, which is what I do to test kernels.

cd /usr/src;make -s installkernel KODIR=/boot/test;cd
nextboot -k test
reboot

This does a one-time start using the test kernel under /boot/test.

Your other option is to describe the problem and ask if anyone using
8-current has encountered it.
