Multiple Ideapad Z570 variants need acpi_backlight=native to force native use on these pre Windows 8 machines since acpi_video backlight control does not work here. The original DMI quirk matches on a product_name of "102434U" but other variants may have different product_name-s such as e.g. "1024D9U". Move to checking product_version instead as is more or less standard for Lenovo DMI quirks for similar reasons.
