After reading Linux Kernel in a Nutshell (by the way, great book), I now have my own kernel configured for my hardware needs. 

However, I have some really strange behavior. On tty1, the same tty that launches X11, I have to press twice each keyboard key. Anyone has any idea what's going on? I am using a customized Debian Squeeze + OpenBox.

Thanks in advance, and thanks Greg for writing the book.
