I met the same problem with M82(RV620).
And I find it's the patch: 100-fedora-vesa-1.3.0-mode-heuristics.patch causes this bug.

I have test it the latest git code of VESA driver and other version driver without this patch, all will work.

Meanwhile, If I add HorizSync and VertRefresh to the xorg.conf, this bug also can be avoid.

Section "Monitor"
        Identifier "Configured Monitor"
        HorizSync 31-38
        VertRefresh 50-60
EndSection
