The linux kernel does have fbcon devices (in general, not in the Kindle's distributed variant, I think), though I guess they don't support 4bpp very well. On the other hand, fbgetty exists.
That said, I'm not sure what is wrong with myts for you. It works without the Java VM of course (its sources are available to check). If it didn't work for you, there's another thing you're missing. One thing that comes to my mind would be simply the standby timeout, after which the keyboard is disabled (look out for the powerd process which manages this).
