The following command will print all optional modules and information about the modules, it also uses less to allow you to scroll through the output.

find /lib/modules/ -name *.ko -printf "%f\n"|sed s/\.ko//|xargs modinfo|less

What do you mean "parameters"? Are you talking about modules
#lsmod | less
