    Hi
I'll try to add an ioctls in my dump driver to print this list. It will
give a good starting point, isn't it ?
The other choice is to create a new modules that use my functions
in firmware.c. But keep in mind that it will usefull only for pa-risc.
I don't know if it is the best practice.

    cheers.
