GTA04 has a W2SG0004/84 connected to UART2 of the OMAP3 processor. A GPIO can pulse the on/off toggle switch.
The VSIM regulator is used to power on/off the LNA of an external active GPS antenna so that a driver can turn the LNA off if GPS is not needed to save battery energy.

Sounds like Greg's going to take the whole series, so for this patch:
