Change SIP and toggle SIP from command line. Assign it to any hardware key to toggle the SIP. This app will allow you to toggle the sip by loading it from the commandline. However, specifiying a command line will cause the PPC to switch to that SIP AND toggle the SIP, so if no keyboard is shown: "SipSwitch.exe Keyboard" will switch to Keyboard and display it. Use the same name as the SIP in the SIP menus.
