I'm back and I was trying to chroot into Ubuntu Core on N900 today. And I've found out that Kernel Power worked (and supposedly works nowadays) with it but stock kernel doesn't. And I use stock one. Maybe will switch back later.
Skry, I suppose you use KP, right? Anyone else with KP chrooted successfully?
PanzerSajt: As of keyboard I will try it, but only on the weekend, I think.
