Public bug reported:

Binary package hint: xorg

xserver-xorg-video-vesa doesn't work when KMS is in use on my machines,
but changing /etc/X11/xorg.conf.failsafe to use fbdev lets failsafe X
work. pm-utils has a method of determining of KMS is in use that could
possibly be used in the /etc/gdm/failsafeXServer script to determine
which driver should be picked for fallback_driver in there instead of
just using vesa.

grep -q -E '(nouveau|drm)fb' /proc/fb

a nouveau KMS fb is called nouveaufb, a radeon KMS fb is called
radeondrmfb and an intel KMS fb is called inteldrmfb. those are the only
use cases of KMS currently.
