It seems not to work.
Created /etc/dracut.conf.d/qla2xxx_omit.conf
# cat /etc/dracut.conf.d/qla2xxx_omit.conf
omit_drivers+="qla2xxx "

dracut  --force "initramfs-3.11.8-200.fc19.x86_64.img" 3.11.8-200.fc19.x86_64
I continue to see qla2xxx inside the generated initrd and server has
problems to boot.

Tried also from command line:
dracut --omit "qla2xxx" --force "initramfs-3.11.8-200.fc19.x86_64.img"
3.11.8-200.fc19.x86_64

but again qla2xxx is inside initrd and booting I have problems..
# gunzip < /boot/initramfs-3.11.8-200.fc19.x86_64.img | cpio
-itdmuv|grep qla2xxx

BTW: where is the old "init" script that loaded the kernel modules in the past?
WHat if I want to manually remove qla2xxx from generated initrd?
