Comment # 3 on bug 1178401 from Fabian Vogt

The initrd is built as part of kernel-obs-build, and kernel-obs-build.spec.in
has this:

# a longer list to have them also available for qemu cross builds where x86_64
kernel runs in eg. arm env.
# this list of modules where available on build workers of build.opensuse.org,
so we stay compatible.
export KERNEL_MODULES="loop dm-crypt dm-mod dm-snapshot binfmt-misc fuse kqemu
squashfs ext2 ext3 ext4 reiserfs btrfs xfs nf_conntrack_ipv6 binfmt_misc
virtio_pci virtio_mmio virtio_blk virtio_rng fat vfat nls_cp437 nls_iso8859-1
ibmvscsi sd_mod e1000 ibmveth overlay"

# manually load all modules to make sure they're available
for i in $KERNEL_MODULES; do
(
  echo "info '  $i'"
  echo "modprobe $i"
) >> /usr/lib/dracut/modules.d/80obs/setup_obs.sh
done

So reassigning back to kernel.
