Bug#565511: ext4.ko module missing from initramfs

[ael <law_ence.dev@ntlworld.com>]

On further investigation, I find that
 /lib/modules/2.6.30-2-686/kernel/fs/ext4/ext4.ko
is missing from the initramfs.

I assume that this explains the failure. I do now seem to remember
 choosing a "slim" initrd during installation. Going into rescue mode, 
I could not find any way to revert to a "full" initrd.

I could not see any bug about this against linux-image-2.6.30-2-686. I 
assume it generates initrd? But then I don't know how the installer can
select a "slim" version.

During my investigation, I noticed that the grub2 entry started with an 
insmod ext2 which seemed a little odd on an ext3/4 system.

So it seems that while the installer supports ext4, the installed target 
system initrd does not.

So I guess that I will have to compile my own kernel on the target and 
then change to ext4 via the rescue mode (it's the root partition) later.
