Answer 1

On tablets I want to show the action bar but still no title bar

The action bar replaces the title bar. There is no concept of an activity having an action bar and a title bar.

Is there a way to show the action bar in fullscreen mode?

AFAIK, no, by definition.

The support library doesn't support the Action bar.

ActionBarSherlock provides a backport of the action bar for API Level 7 and higher.

The easy solution for this according to the docs is to add android:showAsAction="ifRoom" to the menu items. But that does absolutly nothing.

It certainly "does nothing" if you have no action bar. If you want a fullscreen experience, then you will need to roll your own menu replacement. IMHO, most fullscreen apps did this already (e.g., a game going with a game-styled "menu").
