What do you think the average user will care about more? * Seeing kernel oops/panic output about once in a lifetime. * Being able to start/use X in the first place and enabling it to use all of VRAM. Personally, I've never even seen any kernel oops/panic output despite numerous opportunities for that in the couple of months I've been using KMS. But I have spent considerable time and effort trying to get rid of the pinned fbcon BO. If the oops/panic output is the only thing preventing that, maybe that should only be enabled via some module option for developers. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
