I tried what you suggested. However, the video mode is still getting
messed up and causing the above message from the flat panel right after
the "Starting udev" message. Following is the grub entry being used:

title Fedora Core (2.6.18-1.2798.fc6) Text
        root (hd0,0)
        kernel /vmlinuz-2.6.18-1.2798.fc6 root=/dev/VolGroup00/LogVol00 3
        initrd /initrd-2.6.18-1.2798.fc6.img
