Hmm I've been using it a lot over past six months with lapdock with typically updating to Linux next about once a week or every few weeks. I'm just using pending LCD and backlight patches, and omap2plus_defconfig with following patch. Maybe see if you're missing something from that patch? Also Tomi pointed out earlier that n900 needed the analog tv module loaded for LCD output.. I wonder if you need also the pending LCD patches applied?
