I will pay penguinbait a bounty to fix this (as in, I was going to donate after I got KDE running, but then had to remove my new N800's battery for the first time - and second time after discovering that logging out of KDE isn't good enough)

Being unable to lock/unlock is a deal-breaker, it keeps the tablet from being a mobile device because I can't pack it to take with me (grumble grumble no metal case grumble) so I can't use KDE.

Also, I would really rather not need to enter a 5-8 character password to unlock the tablet every time I want to use it - the default maemo way isn't great (compared to the 770) but it does work.
