I don't remember what the "certain circumstances" referred to originally. Right now, if the USB_QUIRK_RESET_RESUME quirk is set (meaning that the device can't reset properly so it always has to be reset-resumed) then persist will be used even if it isn't enabled. Also, that "Later kernels" thing has already arrived. I believe it was implemented in 2.6.35.
