In X, once you analyze scan codes generated by those keys with xev, you can 
assign keycodes locally wih xmodmap. In keyboard maps, you can reuse some 
exotic Fn key names available from historical mainframe terminals, unused on 
PC platform, such as F26 and Shift+F26 and so, I can't now remember the exact 
number limit for function key names, depends on how x libraries built. Works 
great for KDE, which recognizes these names well for shortcuts.
