But we're not just doing variable substitution - we've got to do hash
matching of each KEY_xxx keyword, i.e. parse several strings at startup
when we could just add a note in the fdi file <!-- KEY_EMAIL --> and
have no run-time overhead (think embedded machines)... I'm trying to
make this as fast as possible, and I don't think there'll be significant
changes in existing keymaps.

IMO, A simple howto can show the user how to go from a warning in dmesg
to working buttons (and a patch to hal-devel). Why do you think the
constants are more maintainable than a simple constant with a suitable
comment? Thanks for your help with this BTW.
