Re: Mageia 2 Cannot Install 71.86.15 for Riva TNT/TNT2
Check the changelog of that release. It just adds a check, nothing significant. The release before that was in 2010, it added support for "recent kernels", whatever that meant in 2010. Two years is a long time in the open-source world.
If you have issues with nouveau, then that's what you should focus on. Report to nouveau devs. In the mean time, the nv driver is still around and works for pre-Fermi cards, so that's another option you have.
