I made a few diffs between my old working 2.6.7 kernel and the 2.6.9 and found 
something interesting in fbmem.c:

---------------
@@ -723,7 +419,7 @@
         if (fb_logo.logo == NULL || info->state != FBINFO_STATE_RUNNING)
                 return 0;

-       image.depth = fb_logo.depth;
+       image.depth = 8;
         image.data = fb_logo.logo->data;

         if (fb_logo.needs_cmapreset)
---------------

So, on my 2.6.9, I replaced the '8' by 'fb_logo.depth' and now the logo is 
shown! (but the screen is still not cleared as before when the kernel boots).

Where's the QA guy ? I want to see him now ! ;-)

Cheers,
