[PATCH] ide-devfs.sh update 

Attached is a patch for ide-devfs.sh,
The script is merged with the one from Martin Schlemmer, and cleaned up
by him, to create both types of symlinks with one single rule:

  CALLOUT, BUS="ide", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", ID="hd*", NAME="%1c", SYMLINK="%2c %3c"
