I don't think sd_mod was ever "autoloaded". On SUSE we just load it
manually in initramfs.

And usually distros ship a udev rule like:
  SUBSYSTEM="scsi_device", ACTION="add", ATTRS{type}="0|7|14", \
    RUN+="/sbin/modprobe sd_mod"

I have no idea what makes FC6 behave differently with the
gregkh-all-2.6.20-rc5.patch.

We should probably just add modaliases to the scsi_device, just like we
added to the ide-devices to load the mid-layer modules.

Thanks,
Kay
