   2  * Machine initialization for Dell Axim X3

   6  * For now this is mostly a placeholder file; since I don't own an Axim X3
   7  * it is supposed the project to be overtaken by somebody else. The code
   8  * in here is *supposed* to work so that you can at least boot to the command
   9  * line, but there is no guarantee.
