Check also my thread "Devel upgrades". At least you have to mark as not included clockd and some other packages. They will break your battery status as well as your clock. But uninstalling them and then installing back the versions mentioned in the thread peterleichen linked make it workable again.

It is just that cutetube2 won't work after that (you have to downgrade some qt stuff) and there may be some other things. Maybe a bit unstable sometimes (reboots may accur) but I made the upgrade couple of times and lived with device (both of us, device and I). Just read the thread first.
