Space to ctrl for emacs

I have been using emacs for a few months now and the position of control key had been really bugging me. I always had it in back of my mind that I will have to say good bye to emacs, eventually, because of its key bindings.

Then I came accross a hack that made space key work like ctrl in X. However I could not make it work. In any case, it could not be made to work with a terminal.

But I knew that if I could make the hack work, I will stick with emacs and I really wanted to. So I decided to make a change at kernel level. Below are the changes I made to my kernel. The space key acts like a space key if pressed and released without and other simultaneous key presses. Otherwise, it acts like a Ctrl key.

Since then I have not looked back and my wrists and my brain are now in a happy symbiotic relationship. :)

The code is just a hack and could be improved a lot, but it works for me and I have no complaints after over a month of use.
