Gonzalo,

another thing Nitika and me found,  are the following ::

a)
Ensure that the XO is in normal-mode, and no activity is turned on.

b)
Turn to ebook-mode.

c)
Open "Speak" activity.

d)
OSK appears automatically this time.

e)
Now, pressing the game-key does not cause the OSK to go away :-\
It is only when the "keyboard" key is  pressed, does  the OSK disappear.

f)
If the game-key is pressed again, the OSK appears.


Gist :: Game-key works fine and consistently, when the OSK is required to
be made appeared.
          BUT, it does NOT WORK, if the OSK has been launched automatically.


So, it seems that just hacking onto the game-key won't help :(
