Please investigate - I'd prefer that your patch does not get applied
until we really know what's going on here.
Hmm, if you're using modetest, then userspace is setting a mode, and
userspace is in control of the DRM device - that's probably the reason
why you're not seeing anything happening - modetest probably doesn't
know anything about hotplug events, and so doesn't read the modes.
Have you tried with the framebuffer console and DRM fbdev emulation
enabled, without using modetest?
