Looking into the /var/log/YaST2/mkinitrd.log it has several lines of: W: Possible missing firmware "b43/.." for kernel module "b43.ko" So wasn't dracut just including the firmware files into the initrd beforehand? Anyway output of dracut with --debug is uploaded at https://transfer.sh/NpOo3/dracut.txt (26MB is too big to be attached to bugzilla).
