Does anyone know exactly where in the Registry the list of programs which can rotate is located?

Found the keys at HKCU\Software\HTC\HTCSENSOR\GSensor\Whitelist
Used Jmz and herg62123 Diamond2 G-Sensor.CAB to add a ton of apps to the list. However, IE still doesn't rotate correctly. Almost everything else rotates correctly. The key in the Whitelist is:
Internet Explorer REG_SZ IExplore
Does anyone know if perhaps with the later OS version the key should be different?
