There is first working build on my K3. To install make directory tucnak in your kindle put content of attached zip inside. Run myts and go to tucnak directory and ./run
In Tucnak switch to bw mode - F10 menu and then Setup -> Terminal options.
There is problem with colors, bw mode is not 100% ok and need some work to make it 100% compatible with kindle display..
But tucnak working on kindle...
