Check the parameters passed to a module

["Francois" <francois.rappaz@unifr.ch>]

Hi
I would like to check if parameters pass to a module via a file in
/etc/modprobe.d/ are taken into account.
I have been told that cat /sys/module/psmouse/parameters/proto would
give me the proto value for psmouse, but on my PC (kernel 2.6.9, with
udev) I have only a fcnt file (or somthing like that) under psmouse.
The only way I seen is to pass a wrong parameter with modprobe and the
check dmesg (to see invalid parameter for psmouse)
Is there any way to check the parameter pass and there value ?

TIA
Francois
