JFYI -- recently I wrote a MI driver which supports both the LCD panel and
buttons, it is currently being reviewed by the port maintainer. If anyone
wants to give it a try please download the patch using the link below, apply
it to the 1.6 kernel and then let me know if it works.

The driver still needs some testing, indeed.

SY,
