kernel26.img trouble

Hi

I'm trying to trim down the hooks used by kernel26.img, however I am running into some troubles.
Init can't simply find /dev/sda5 (its root "/" mounted as ext4).

I'm using these modules for my HDD and filesystem:

poul ~ $ lsmod | grep ata && lsmod | grep ext && lsmod | grep rei
ata_piix               23300  5 
pata_acpi               6016  0 
ata_generic             6788  0 
libata                158112  3 ata_piix,pata_acpi,ata_generic
scsi_mod              102164  4 sg,sd_mod,sr_mod,libata
ext2                   66184  1 
ext4                  216348  2 
mbcache                 8708  2 ext2,ext4
jbd2                   54808  1 ext4
crc16                   3712  1 ext4
reiserfs              231424  1

This is my /etc/mkinitcpio.conf which seems to include the right modules:

MODULES="ata_generic ata_piix pata_acpi ext2 ext4 reiserfs"
BINARIES="/bin/mknod"
HOOKS="base udev keymap"

This is a "log" when issuing $ sudo mkinitcpio -v -g /boot/kernel26.img:

It seems to include the right modules here aswell, but still /dev/sda can't be found.

Here some extra info:
$ hwd -e

-snip-
8086:24ca IDE interface: Intel Corporation module: ata_piix 
          82801DBM (ICH4-M) IDE Controller
-snip-

lshwd says that I'm using piix, but I have not used that module for some time:

-snip-
00:1f.1 Class 0101: Intel Corp.|82801DBM IDE Controller (UltraATA/100) (piix)
-snip-

Some info from dmesg:

Can somebody see what I am missing?

In advance thank you.

Re: kernel26.img trouble

I think you have to include the module sd_mod as well.
