The FreeBSD wiki is a collection of pages, I need to know which specific 
pages contained your instructions.

This is a standard way to install a new kernel.

I think the output of pciconf -lv might help as well.

You should be able to boot back up in your old kernel so you can at 
least get back to your previous working conditions. When you boot the 
machine, and you see the boot menu, select the option to escape to the 
loader prompt. Here, 'unload kernel' and 'load /boot/kernel.old/kernel', 
then 'boot' to start the system. Whenever you make installkernel from 
the source tree, it will back up your old kernel and modules in 
/boot/kernel.old. Alternatively, you can move /boot/kernel to 
/boot/kernel.bak and move /boot/kernel.old to /boot/kernel to restore 
your original kernal and modules, and reboot the machine.
