Hi, second installement of my mini-series:
The AT keyboard driver assumes that the keyboard is set to scancode set #1. It seems like many keyboards use set #2 (or even #3) by default now, and some 8042-emulating chipsets don't enable translation (to #1) by default. The BIOS then enables it to support the legacy compatibility the PC architecture is famous for - but CoreBoot doesn't. http://osdever.net/ has some information on programming the 8042 (without BIOS calls), incl. how to configure the scancode set you want to have. Also, 0x01 is the scancode for ESC. I didn't look if there's a special case for escapes, but a simple "\e" instead of "\0" at that code point might help.
