I didn't have to tweak modules.conf at all on 5.3. I'll admit that
I didn't test asterisk on FreeBSD without zaptel though. It might
run perfectly fine without zaptel. After all, the zaptel driver is
a really old version, and still GIANT locked....

No. And I don't plan to. I'm quite familiar with both Linux and FreeBSD.
I used to run it on my laptop, as well as servers. I know when FreeBSD
is being operated outside of it's sphere of stability. Zaptel, at least,
appears to push well beyond that sphere for now.

Why put myself through the hassle when Linux is just as good?
