As noted in comments on earlier posts, I gave up with my X102 and returned it to the shop.
In the main I was frustrated by the poor display driver support and issues with power/brightness control.
I replaced it with a Toshiba NB10, which I’ve had much more success with. I started a similar site to record my progress with it at http://unofficialnb10.wordpress.com/
I’ll leave this site up, and I’m happy to accept any posts anyone wants to contribute or links to other sites with information about the X102.
Thank you to all who commented.
