This won't work. Under the old behaviour, if you were owner of the tty, 
you were boss of its keymap. Code was added that checks for explicit root 
permissions (actually CAP_SYS_TTY_CONFIG, but this is root in practise), 
so, currently, nothing regarding permissions works.

I agree, that setting a permission would be ideal, this way the sysadmin 
can enforce his prefered policy, rather than having it hardwired into the 
kernel.
