Ick.  First a few general comments on procedure:
  - please CC: linux-hotplug devel, or linux-kernel with core stuff like
    this.
  - your patch was line-wrapped, and could not be applied :(
  - No Signed-off-by: line as per the rules specified in
    Documentation/SubmittingPatches.

Ok, now, what exactly are you trying to solve here?  With 2.6.14 and
udev handling the hotplug control, you should not see any need for a
change like this.
