Yeah, the modprobe blacklist is one of those “someone needs to write a gui for the common use cases, but no-one’s been bothered enough yet”. To some extent this is because it’s essentially a nasty hack to work around dodgy drivers, but that’s always going to be the case for some drivers.

(FYI, I just filed http://brainstorm.ubuntu.com/idea/23776/ which might get something done eventually…)
