You could use add your options to modprobe.conf. You will probably need to run "depmod -a" and "mkinitrd" afterwords. The module is probably loaded while the kernel is still running in ram (initrd). You might want to extract the filesystem in initrd and check if the module is in there.
Code:
options modulename option...
This command allows you to add options to the module modulename
(which might be an alias) every time it is inserted into the
kernel: whether directly (using modprobe modulename, or because
the module being inserted depends on this module.
All options are added together: they can come from an option for
the module itself, for an alias, and on the command line.
Also read the kernel source documenation for the kernel options. I think if a module isn't built in, the option is passed on to modprobe. I believe that it is possible to include kernel boot options for loadable kernel modules. However, using modprobe.conf or a file in /etc/modprobe.d/ is how it should be done.

Note, here is how you can examine your initrd file from your home directory:
mkdir initrd
cd initrd
cpio -vid < <(zcat /boot/initrd)
