Ah, but this is normal. It is not the grey bar that people with an N9
have been complaining about. See the grey bars at the bottom on
the screenshots over here:

On the N9, I start a midlet in full screen to hide both the top bar
and the bottom bar. On the N900, I don't (because there is no
grey bar). However, if there is a general interest to always start a
midlet in full screen to hide the top bar as well, I can do that.

Actually, you can enable full screen with the Ctrl+Arrow Up key combination.
