Successfully flashed both an XO-1 with update-nand [1] and an XO-1.75 with fs-update.

Yes, on the XO-1.75 after disabling powerd to prevent the lockups at idle suspend, the track pad feels a little spongy/laggy but it might just be different accel. settings, not sure?

The XO-1 (original trackpad) is notably worse, if you trace circles the cursor stops from time to time along the path. Also had the cursor stall completely twice and then slowly stutter, perfectly vertically, every few seconds down the screen; then fluttered randomly vertically very fast and disappeared (keyboard and UI still worked OK).

Yes same here on the XO1.75. It also fails to create or connect to an ad-hoc network, the three icons are shown in neighbourhood but have no 'Connect' ability.

The neighbourhood view on the XO-1 is showing AP's just fine, connected to my AP without issue.


[1] Spent a long time looking for the wiki page Daniel wrote that described the ofw install command for .onu and .uim files on the XO-1 but could not find, an old email thread archive via google to the rescue.
