thanks for clarifying that. I also noticed that and commented in #751275 but it was too late back then. > I suspect the best solution for uvesafb/fglrx users like Lukas might be to > blacklist drm.ko so it is never loaded.

It seems that i915 has to be blacklisted as well because i915 loads drm and "blacklist drm" doesn't prevent that. Shipping that in a default configuration would break too many things, I suppose.
