I'll ask if that helps w/ the other bug. Nevertheless, having modprobe.blacklist working by default on the installer would be interesting. I passed around a sed line to use modprobe -b on hw-detect, a simple workaround, but that definitely isn't convenient (neither for preseed). And since I don't know much of modprobe and its usage on the installer, I decided to reach out for you guys first. Now that is seems to be clear, can get hw-detect be updated to use modprobe -b ?
