Hi,
Oh, thanks for that screenshot.
Yes, that makes sense.
It looks like that this is happening on your boot partition already, so the kernel is bundled with aacraid to be loaded at boot time.
The /etc/modprobe.conf file is not available at that time, so it makes sense that you can't blacklist it that way.
In order to resolve this you would have to fix the initrd image to not try and load the driver and for that you would start from a CD in rescue mode.
Sorry I don't have exact steps, but the following links might help:
