It should be pretty easy to figure out the right string for DMI autoloading. Just do a cat /sys/class/dmi/id/modalias and replace the part of the string you consider not very useful for identifying the machine with (dates, version numbers, empty strings, 0123456 rubbish data, ...) with an asterisk.
Looking at those strings included in your patch they look pretty much correct, but since I don't have access to a Mac I cannot really check this.
It's udev's job to match the modalias strings of your driver module with the modalias string from /sys/class/dmi/id/modalias. You can retrigger this matching by doing something like "echo 1 > /sys/class/dmi/id/uevent" or suchlike, but I don't remember the details.
