I checked the archives and no one has posted a message on MTRR overlaps since
2002. At that time, Andrew Rodland wrote something about what appears to be this exact problem; a link to it is
Haven't bothered. But I'm getting those errors and the inability to set up MTRR's by X too.
I've got a hunch that in my case it depends on how big MTRR vesafb driver sets up for itself during boot ... if it's the same size X later asks then everything is ok.
Usually it's 16MB for vesafb in my machine and 32MB for X. So i've always just disabled the MTRR set up by vesafb (echo "disable=n" > /proc/mtrr) and restart X before playing games. This way no problem.
