I did slip to another project, but good that the i2c probe did find your chip.
Altough offtopic;
I just got one OLED display connected to the phone

Interface uses ioctl to talk over i2c
Code:file=open( "/dev/i2c-1", O_RDWR ) ioctl( file, I2C_SLAVE, 0x3c) write(file, buf, len)

Yes I have been asking around. I just don't get that when the phone was announced everyone was shouting "qwerty slider!!" and when there almost is a working prototype it becomes very silent

If I've read it correctly, on a keypress this should happen:
-key press
-key release
-the chip stores the most recent key press
-this is stored on input report
-the chip sends out an interrupt signal
-phone notices interrupt
-the phone uses get_report to read the input report
-phone read input report
-the interrupt signal is killed and input report is cleared by resetting the chip
-start over
