Hi !

I used to have a nice vga boot logo with my 2.6.7 kernel, but with the 
2.6.9, my
boot logo has disappeared (same .config)...
It seems to switch to VGA, and some space is reserved for the logo, but 
it is not displayed.
The logo appears with vesafb.

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,
