Microsoft ergonomic natural keyboard 4000

[Roey Dror]

I just received the keyboard specified in the subject. It seems that the 
standard keys work well.
I was wondering  if there is any way  to make all the  "Special keys" 
work.  When I searched the subject in google, some users suggested 
loading a module called msnek4k or usbnek4k.
I seems there is no such module in my current system and searching a 
package for this module in yum had no results.
Is there any way I can make all the special keys work without 
recompiling the kernel?
