The latest Apple MacBook (MacBook5,2) doesn't reboot successfully under Linux; neither the EFI reboot method nor the default method using the keyboard controller works (the system just hangs and doesn't reset). However, the method using the "PCI reset register" at 0xcf9 does work. This adds a quirk to detect this machine via DMI and force the reboot_type to BOOT_CF9. With this it reboots successfully without requiring a command-line option. Note that the EFI code forces reboot_type to BOOT_EFI when the machine is booted via EFI, but this overrides that since the core_initcall runs after the EFI initialization code.
