I tried this patch and kwin still crashes in QEMU, but at a different place
now at least:

At this point `export KWIN_DRM_NO_AMS=1` helps though and the session starts
up. Unfortunately kwin_wayland gives up just after these messages:
kscreen.kwayland: Loading Wayland backend.
kscreen.kded: PowerDevil SuspendSession action not available!
kscreen.kwayland: Loading Wayland backend.
kwin_wayland: Couldn't find current GLX or EGL context.
and crashes somewhere in the destructors of Qt's global objects.
