If VGBS is not called on boot, the firmware sends an initial 0xcd event shortly after calling the BTNL method, but only if the device is booted in the laptop mode. However, if the device is booted in the tablet mode and VGBS is not called, there is no initial 0xcc event, and the input device for SW_TABLET_MODE is not registered up until the user turns the device into the laptop mode. Call VGBS on boot on this device to get the initial state of SW_TABLET_MODE in a reliable way. Tested with BIOS 1.13.1.
