Remove ancient documentation of IBM RapidAccess keyboard hack

Keyboard setup belongs in drivers, not in a document no one sees
because we don't even install it.

-The IBM Rapid Access keyboard have some extra buttons
-on it to launch programs, control a cd-player and so on.
-
-These buttons is not functional when the computer is turned
-on but have to be activated by sending the codes 0xea 0x71
-to it.
-
-I've written the following hack to send codes to the keyboard:
-
---------------------------------------------------------------
-/* gcc -O2 -s -Wall -osend_to_keyboard send_to_keyboard.c */
-#include <stdlib.h>
-#include <unistd.h>
-#include <sys/io.h>
-
-int main( int argc, char *argv[] )
-{
-  int i;
-
-  ioperm( 0x60, 3, 1 );
-
-  for( i = 1; i < argc; i++ ) {
-    int x = strtol( argv[i], 0, 16 );
-
-    usleep( 300 );
-    outb( x, 0x60 );
-  }
-
-  return 0;
-}
---------------------------------------------------------------
-
-As root you can then call this program (in your boot scripts)
-as "send_to_keyboard ea 71" to turn on the extra buttons.
-
-It's not a good idea to run several instances of this program
-at the same time. It is a hack but it works. If you try to
-send other codes to the keyboard it probably will lock up.
