In that case, one solution would be:

* using the full 32 bit scancode
* add a module parameter to squash the ID byte to zero
* default the module parameter to true
* create a keymap suitable for ID = 0x00

Users who really want to distinguish remotes can then change the module 
parameter and generate a keymap for their particular ID. Most others 
will be blissfully unaware of this feature.
