To be sure - does it hang without at_keyboard as well? keylayouts is 
loaded automatically as dependency of at_keyboard anyway, and it is 
quite unlikely anything in this module would cause observed effect.

First try to reproduce it without GUI  - it is rather hard to see 
anything in this case. Just boot grub without any grub.cfg - you will be 
left in plain CLI. Now try

insmod at_keyboard
terminal_input at_keyboard

does it still work? If yes, try keymap /grub/layout.gkb; does it still work?

and to be sure - could you send me your gkb file for test?
