If you hit the keyboard at the "wrong" moment during keyboard
initialization, the keyboard driver may get confused.
In your case, you type something before the kernel is loaded and that
seems to be causing the trouble.
Such key input should be discarded by the keyboard driver before it
tries to initialize the keyboard. There may be a nasty timing problem
here...
As a temporary workaround, please apply the following patch to
/sys/dev/atkbd.c and see how it works.
