bktr problems

[Naram Qashat]

That's a little helpful.  How do I determine what values to use?  And what's
the easiest way to test the changes?  Right now, I've got the bktr module
compiled directly into the kernel.  But last time I tried to not compile it
into the kernel and load it as a module seperately, it failed to load, I
think it might've been because of the other device lines that the bktr page
in the FreeBSD handbook says are needed.
