What I'd do in this case would be this: 1. Initially have the M* level-shift keys assigned KEY_RESERVED 2. Have a big enough keymap to map all keys in all M*-level shift states possible. Eg: START OF KEYMAP M* keys 1st set of G* keys 2nd set of G* keys 3rd set of G* keys... ... last set of G* keys END OF KEYMAP 3. Have the driver special-process M* level-shift keys *as long as they are still set to KEY_RESERVED* to select which part of the keymap is used to translate the other keys. Note that this likely means pressing a M* key would be transparent to userspace in this case, i.e. no events would be issued when a M* key is doing a level shift. So, you'd be able to set all mappings you want in the driver, and the M* keys would do what they're expected to do without any userland help at all, but you'd still be able to program the M* keys to be normal keys if you want. Of course, this assumes you don't do chording on multiple M* keys to end up with a huge number of keymaps :p -- "One disk to rule them all, One disk to find them.
