	Hello,

	one way to try to make support progress would be to run the decoding 
scripts I posted earlier on these logs, then compare how registers related to 
GPIO are set and compare to a test run of the current backend implementation. 
Then change code to handle the differences.
	Personnaly I haven't yet enough time to help for this model. Maybe at the 
end of April.

Regards,
	Stef
