[CentOS] Keyboards

On my new Dell system, it's got a cardreader. More to the point, it's got
an idiot menu key... *right* next to the right control key, and just where
the annoying keyboard design has it cut down from the oversize space bar
ASCII art

<ctrl><WinDoze> <tall[                ]<tall<tall<tall  <ctrl>
                 Alt>[ tall spacebar  ] alt> Win> menu>

The result is that just trying to type, I regularly hit the thing. Does
anyone have an idea how to disable this forever (if y'all don't, I'm
prying the key *off*).

Thanks in advance.
