I got a confirmation from Peng Tao (the patch author) that this is indeed
a case here.

The patch works fine for me so just in case if somebody runs into the same
issue I'm posting the current F11/x86 grub package with ext4 support here:

http://www.kernel.org/pub/linux/kernel/people/bart/f11/

grub-0.97-50.fc11.ext4.i586.rpm
grub-0.97-50.fc11.ext4.src.rpm

[ Please note that doing grub-install is needed after installing it. ]

Thanks.
Bart
