Hi Dmitry
thanks for the reply. I test this, it's not work. 
----------
$ loadkeys -m defkeymap.map > defkeymap.c && rm defkeymap.o
loadkeys: defkeymap.map:71: adding map 64 violates explicit keymaps line


I look into the keyboard.c,  in the kbd_keycode function
seems this "keysym = key_map[keycode];" make the CtrlL and CtrlR 
map to the Ctrl. so I change the keyboard.c[1] code like:

1. when press CtrlR pass, change back the Ctrl to CtrlR. 
2. in the k_shift function set a sign [shift_right] to 1
3. change the CtrlR to Ctrl in k_shift funtion. other code 
   will only know the Ctrl. not the CtrlR. 
4. when press "u" and [shift_right] is true change the keysym to "1"
   others are same.

_I think the code is not good. so if someone have any idea._
_just let me know._

thanks.
