Since meta are huge, I can not pass them as parameters. Most distributions have tools to save and restore the state of the system random number generator, /dev/random, on startup and shutdown. I recommend following a similar approach with your module: you could have a script that loads your module and then pushes configuration information into the kernel with a character device, proc file, or filesystem. A similar script for shutdown could retrieve the configuration data from the module through a character device, proc file, or filesystem, and then unload the module. -- Demand voting integrity: http://verify.stanford.edu/evote.html
