Disabling Super key?

[Girish Kulkarni]

Is there any way I could disable the Windows key on my keyboard?

I use FreeBSD 7.0-RELEASE on a Dell Inspiron 640m laptop. My Windows
key ("Super_L") has developed a problem for some unknown reason: it
gets pressed and remains so without my touching it. I could diagnose
this only using xev, which reported a constant Super_L KeyPress event.

This means that I cannot enter text in for example Firefox or Emacs
most of the time and this is terribly irritating. I could probably
solve the problem by disabling the Super key.

Thanks,
Girish.
