Restoring kernel input driver state on boot

Hi,

Since is not possible for a kernel driver to save anything to a file I need to know how could I achieve that using other technic.

Someone mentioned earlier in this list that I could use udev to load settings on a kernel module.

Since my module state depends on a whole structure the best thing I can remember to achieve this goal is someting like this:

- In user space (and since i'm always exchanging that data from and to the kernel module within my device control panel) I could save to a fixed place a file with that state.

- With a custom and small utility I could load (using the binnary attributes) that state to the kernel module on it's initialization using for that udev.

Since my understanding of udev at this point is almost null, I would like to know if this is possible, and in what functionality of udev I should put my effort on.

If someone could give me an expert advice about I would really appreciate it.

Thanks in advance,

With my best regards,

Nuno Santos
