Solved. If you're trying to configure module 'n', you must reference
it with 'n+1' in zaptel.conf and zapata.conf.

In other words, I changed these lines and now everything is detected fine.
; zaptel.conf:
;fxsks=3
fxsks=4

;zapata.conf
;channel => 3
channel => 4

Thanks to gonzo in IRC for the tip.
