The blacklist is only used to ignore a module's internal aliases unless the --use-blacklist option to modprobe is specified.  Since the zaptel init script loads the modules by module name and not by their PCI aliases, the blacklist will not prevent it from functioning as intended.

There are ways to modprobe arbitrary modules before udev runs, but nothing that is touched by a standard install of zaptel (as far as I'm aware).
