There is a commercial product available -- look at
  http://www.vetra.com/Elimina2.htm  $49/each

Black Box also made the "Keyboard Ghost" but all I can find on their
website today is the "Mouse Ghost". It was more expensive ($79 I
believe).

A much cheaper possibility is to check the BIOS error-reporting
settings -- many allow you to set them to ignore keyboard errors. If
you can do that there is no cost at all!

Another cheap (but somewhat ugly) solution is to take apart old
keyboards (which are almost a dime a dozen at thrift stores) and chop
off all the keys (they're normally-open switches, so the keyboard chip
won't notice their non-existance), which makes a much smaller package
than the full keyboard. But then you have to put the remainder in some
sort of box or pot it in epoxy.

You could to a Google search on "keyboard emulator" to see other
approaches.

There was an article about this very subject in the July 2001 Nuts 
& Volts magazine.  The guy ended up building a keyless keyboard 
emulator, consisting of a small microcontroller chip, and about 5 
discrete components.  He used a PIC 16F84 and built it into a little 
perfboard gizmo.  The Nuts and Volts website is at

http://www.nutsvolts.com/toc_Pages/jul01toc.htm

But they don't have a full copy of the article on the site, just a
link 
to the code for the PIC.  If you're up to doing a project like this, 
including burning the code into the PIC, I could send you more 
information on it.

According to the article, it really is more than just a little dummy 
thing; it has to have at least some intelligence, since one of the 
things that occurs during the POST is a check, where the PC ROM 
is looking for particular responses from the keyboard.

Hope this helps,
