TI ship TCA8424 which pushes HID over I2C at 1mhz.
The chip is preprogrammed for standard laptop keyboards but supports up to 128 key/function inputs including multiple simultaneous key entry (great for all those function/ctl commands)
while it is built to support Win8, there is a lkddb entry for HID_I2C which may be possible to build into the Mer kernel adaption by default.
using this chip would only require physical hardware construction of the KB using the pin/wire connections as defined by the TCA8424.
i'm waiting on word back form lbt and Jolla and if they are good to go, I'll by e TCA8424 dev kit and start trialling.
I need to see if the HID_I2C driver can also push input directly into Malit.
stay tuned as more info comes to hand....
edit: if the kids give me break this arvo, I'll try a kernel build with HID_I2C and see if I can get it up on my Raspberry Pi with Mer. if this works, we'll take it form there...

You got confirmation from Jolla?
That chip looks awesome! Does this mean that your proposed chip will work for a keyboard OH?

Beat me to it 
I'm waiting on word from Mer team. Anyone who can get on IRC in the mean time is free to ask too. (stuck at work at the moment).
If true, and HID over I2C is supported, life gets a lot easier.
Will troll mer kernel conf. files tonight to see if it's already in the arm build, as I couldn't find it in PC builds today

Seems the community is to fast for Jolla ;-) Great job guys, very interesting to follow that development & read this thread. My greatest respect!

Isn't a interrupt lane still important, if not, why not?

The pcb is done! No shorts, gpio expander in place, pullup resistors in place (on the back) and a switch to simulate sliding out.
Now it is time to do some software!

Yes I checked, no shortage and it connects nicely when keys are pressed!

I've just received my first 3D print. I wonder if I should tear my n900 apart and start building something around it (PCBs and MCUs I'm already familiar with)
