dmesg output just after attempt to switch to 800x600 and recovery

When I boot up and login I end up with the desktop in 1680x1050 resolution. I
can do scaling to get other effective resolutions, but if I actually try to
switch the used resolution to any of the other availble ones (e.g. 1280x1024,
800x600) I end up with parts of the output scattered all over the screen in
medium sized blocks. Usually the screen will switch back to 1680x1050 and work
OK when I don't confirm I want to stay in the new resolution, but sometimes
things end up messed up when it switches back and I ned to shutdown to recover.
I am using x86_64 Fedora 21 with various kernels. I have seen this issue with
the normal 3.17 kernels, 3.18 rawhide nodebug kernels and the mainline 3.19
kernel (the latter fixes another Nouveau problem I had).
Currently mesa is at 10.4, though I think it was at 10.3 when I first switched
this machine over to linux and I still had the same issue.
The reason I care about this is that I want to play some games in wine that use
800x600 and the workaround of using xrandr scaling before and after slows
things down and is ugly.
