Got my T91 this week; will be looking to install Crunchbang Linux on it this weekend, hopefully tomorrow. Going to try CrunchEEE/Crunchbang Lite. The Live boot from usb worked fine, with only one odd problem (it froze as if it was paused or you had closed the lid, only to be resumed by pressing the power button, but this didnt seem to cause any ill effects).
As with everyone else, the wireless didn't work out of the box and the video drivers need sorting, as well as a decent touch calibration and right click simulator. Definitely need a good right click simulator as CrunchBang uses OpenBox.
Sounds like you've all done fantastic work fixing the issues so far, I'll let you know how my installation goes
