The new ISO has been just upped. It includes all the drivers from the previous 10.5.5 release (with all the PPFs) plus some new kexts for 10.5.6.
Please test; 10.5.6 has introduced some changes and some of the old drivers might not work (could even generate kernel panics). As always new add-ons and bugs will be handled by PPFs.
Enjoy!
