I installed (rpm -Uvh) this kernel on top of 883:

http://rpmdropbox.laptop.org/f14-xo1.5/kernel-2.6.35.13_xo1.5-20120508.1139.olpc.eb0c7a8.i586.rpm

It booted fine, but the touchpad does not work, keyboard does, network does not, lego tower does not. 

Should I have done this differently? Any advice how to diagnose this, and get the machine working correctly again?

Thanks!
