Analog input with zeemote JS1

[subsist]

I'm using a zeemote JS1 to play MGS with FPSE. Is it possible to map the zeemote's hardware analogue to the FPSE software analogue stick?
I am absolutely certain that the zeemote JS1 outputs in analog but so far I can only map it's directions to the dpad functions in FPSE. Obviously there would be much greater precision for games where aiming is required, if this function was available.

I'm playing with HTC desire on (rooted) cyanogenmod7 with the bluezIME driver for pairing with the zeemote.
