I know, thats why I asked.

In Archlinux, I copied console keymap

,---------------------
| de-latin1-nodeadkeys
`---------------------

adapted it to my emacs needs, saved it and put

,----------------------------------
| KEYMAP=de-latin1-nodeadkeys-emacs
`----------------------------------

in my /etc/vconsole.conf. 

It looks somehow like this:

,--------------------------------------------------------------------------------------
| # de-latin1-nodeadkeys-emacs.map: German keymap with special keybindings for Emacs
| 
| include "de-latin1.map"
| 
| # control keycode   7 = Control_asciicircum
| keycode  13 = apostrophe       grave
| keycode  27 = plus             asterisk         asciitilde
| # keycode  41 = asciicircum      degree
| 
| # corresponding keys in de-latin1.map:
| # keycode  13 = dead_acute       dead_grave
| # keycode  27 = plus             asterisk         dead_tilde
| # keycode  41 = dead_circumflex  degree
| 
| # unterste Zeile:
| keycode  29 = AltGr             AltGr           AltGr           AltGr
| [...]
| etc etc

Would be interesting if (and how) it works to actually define and use a
hyper-key on the console, because even the standard modifiers like C-,
M- and don't always work, especially when combined (see 'org on a
tty' in the manual) or in combination with S-.

sounds interesting ...
