Thanks in Advance. > It's not a bug, it is a feature of the syscons driver. There are basically two ways to change this. One is to go into /usr/share/syscons/keymaps/ and find the file corresponding to the keymap you use and change any 'boot' entries there to somthing else (like 'nop'). (This variant is in the FAQ.
