For me it is somewhat usable under KDE, although it does take over a minute to load, and it seems to crash randomly for no apparent reason.

In os2008 it pops up the hildon keyboard when a text field is selected but no text gets entered into it. However kvkbd loads in os2008, and it works to input text.

Flash works with it even in KDE.

I hope an updated package gets released soon, that is a lot less buggy.
