Subject: [PATCH] FS#11199: ipod bootloader: reboot to disk mode on cable
 insert, following a fatal error

If the ipod bootloader dies with a fatal error it prompts you to press buttons to reset and enter disk mode. With this change it now also polls for USB/firewire insertion and if the cable is detected, it reboots to disk mode directly for you, avoiding user problems with rebooting correctly by hand.
