I just downloaded the latest kitchen stuff from
http://ppckitchen.org/ and cooked a WM6.5 ROM, so the kitchen's shouldn't be dead. Head over there and download the Kitchen Installer and that should get you cook'n.
Once you install the PPCKitchen, run the Updater to make sure you have the latest kitchen files. Sorry though, I can't remember off the top of my head of the 20755 kitchen was once of them.
