Thank you.
I do not have the file /etc/modprobe.conf

Besides, I  think what I want to do is little different, as I want to be
able with grub to change the value assigned to mymodule's argument.

Essentially, I have mymodule.ko. If i do insmod mymodule.ko
param="valueOfParam" I can see everything works (looking at /proc/devices I
can see mymodule has registered) and I can read param (the read function
implemented in mymodule just returns the value of the string module argument
param.

What I would like to do now, is to use grub and do something like
ttile Fedora
     root (hd1,0)
     kernel /vmlinuz-2.6.30.9 ro root=/dev/....
mymodule.param="valueOfParam"
     initrd /initrd-2.6.30.9

Tried several things so far, but with no luck.

Thank you
  Luca
