Show Grub2 Splash Screen with quiet Grub

[Spengler, Johann]

Hello everybody,
this is a cross-post from askubuntu.com 
(http://askubuntu.com/questions/352259/show-grub2-splash-screen-with-quiet-grub)
 where I did not get any reaction for almost a week.

I also searched the archive where someone had a similar problem, but got no 
answer either: 
http://lists.gnu.org/archive/html/help-grub/2012-06/msg00026.html.

So now I hope that someone here can help me with the following problem:

As the grub splash screen shows far longer than plymouth on my box, I wanted a 
nice background there as well. I set it up, but it only works when GRUB_TIMEOUT 
is greater than zero, although this post 
http://ubuntuforums.org/showthread.php?t=1302743 says:

    To hide the menu on boot: There should be no # symbol at the start of the 
line: GRUB_HIDDEN_TIMEOUT=0 line. "0" in both entries (GRUB_TIMEOUT & 
GRUB_HIDDEN_TIMEOUT) above should boot the system without a timeout. A positive 
integer will leave a blank screen for that number of seconds, allowing the user 
time to press "ESC" or "SHIFT" to display the menu. The splash screen will 
still display during the timeout.

So I do not want the grub2 menu to show, but the grub2 splash screen. Is this a 
bug? Can I fix it?
