Description of problem:
When booting 2.6.10 kernels with graphical boot enabled ("rhgb"
specified in /etc/grub.conf), I expect the graphical boot screen to
fill the physical display.  Instead, the graphical boot screen is
offset downwards by about 10% of the height of the physical display. 
The top 10% of the display contains what appear to be randomly colored
pixels.  Due to the offset, the bottom 10% of the normal graphical
boot screen is not visible.  After the system completes booting into
runlevel 5, the display is correct (the login screen fills the display).

I see this problem (the offset) when booting the 2.6.10-1.8_FC2 and
2.6.10-1.9_FC2 kernels as well as when booting a vanilla 2.6.10 kernel
downloaded and compiled from www.kernel.org.  When booting the
2.6.9-1.11_FC2 kernel, the problem is not present (the graphical boot
screen fills the display).

I do not know if this is an issue with rhgb that was uncovered by the
newer kernels, or if the problem lies in the 2.6.10 kernel.


Version-Release number of selected component (if applicable):
rhgb-0.11.2-6

How reproducible:
Always

Steps to Reproduce:
1. Press the power button
2. At the grub menu, choose any installed 2.6.10 kernel
3. 
    

Actual Results:  The graphical boot screen is shifted downwards, and
the top of the display is filled with scrambled pixels.

Expected Results:  The graphical boot screen should fill the display.

Additional info:

This problem is occurring on a Gateway 200 laptop.  All installed
kernel RPMs are i686 architecture, and the Video card is identified by
hwbrowser as an Intel 82852/855GM Integrated Graphics Device.
