No. The proper way to set module parameters is in /etc/modprobe.conf or 
in a file under /etc/modprobe.d (depending what your distribution uses .
modprobe of 2.6 can use either). Put there the line:

  options wct4xxp t1e1override=15

I hope noone still uses 2.4 nowadays but there are some equivalent files
for the 2.4 modutils.

That hack of the zaptel init.d script means that if you just run
'modprobe wct4xxp' those arguments are not used. Which is why I
recommend noone to use it.

In fact, I'd like to deprecate it for exactly that reason.
