Sorry my bad. It actual works compiling the module into the kernel and then using module.param=value sintax.
Sorry again.
Thank you, Luca

You are right. My module has been compiled into the kernel though. But when the kernel starts I do not see it registered.
This is what I did 1)saved my module .c file in drivers/crypto/ 2)edited drivers/kernel/Makefile adding obj-$(CONFIG_CRYPTO_MYMODULE) += mymodule.o 3)edited the drivers/crypto/Kconfig adding config CRYPTO_MYMODULE tristate "My module test" help Enable to test it
4)make menuconfig => setting my module to be built into the kernel
Thank you, Luca

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.
i'm pretty sure that you can only use that "mymodule.param" notation on the kernel command line for modules that have been *compiled into* the kernel, no? that won't work for loadable modules, but i'm willing to be corrected.
