It happens with modes lower than 320x240 which is already a bit gibberisch

when using gvid to change resolutions it first used only the resolutions I had
defined in the 'Section "Screen"' but now it lists every resolution it can
think off.

I had tried with drm and dri off, and even with a plain vanilla XF86Config.
When investigating things I also discovered drm wasn't working anymore either:

(II) MGA(0): [drm] failure adding irq handler, there is a device already using that irq
[drm] falling back to irq-free operation
(==) MGA(0): Direct rendering enabled

but glxinfo claims not.

(config, logs and dmesg available upon request)

Yes I can connect to it from remote, but the Xserver is using up all CPU
making killing it a bit hard sometimes.
