I built my own xkbd for 2008. Never noticed any of the problems you are having.

The big issue, however, is that you can't use the ENTER key properly. My guess is that the libraries have been modified so that pressing the ENTER key brings up the full screen finger keyboard and when using the Hildon keyboard it passes something differently to the dialogs.

It is these small things that really drive me crazy and make doing things your own way extremely frustrating on the n800.
