Sorry, I don't have a remote, so I can't really help (coding-wise) here.

The reported GPIO readouts so far doesn't have 0x01000 (bit12) enabled.
Most people are seeing 0x30000 (which is similar to your no button pressed
case). I wonder if 0x01000 (bit 12) is set at a later time?
So I *guess* the GPIO map for FV2K/FV3K looks like the following:
Bits: 27-25 24 23-21 20 19 18 17-16 15-13 12 11-0
RemIn ?? RemIn ?? ?? BtnIn ????? AMuxOut ?? ????
RemIn: Remote Input Value (Input)
BtnIn: Button Pressed (Input)
AMuxOut: HEF4052 Analog Mux Enable & Select (Output)
????: Unknown (I'm assuming the constant bits, e.g. b16-17, may be other
inputs like the Resistor pad Configuration)
