With `dtoverlay=vc4-kms-v3d` in /boot/config.txt, dmesg output seems correct:

With the Xorg conf from fbturbo, /etc/X11/xorg.conf.d/99-fbturbo.conf, Xorg starts, but its log doesn't mention vc4, and the vc4 driver is not used, that is glxgears reports llvmpipe:
$this->bbcode_second_pass_code('', '
$ glxgears -info
GL_RENDERER = llvmpipe (LLVM 7.0, 128 bits)
GL_VERSION = 3.1 Mesa 18.3.1

')
Without the 99-fbturbo.conf, Xorg crashes immediately (I run openbox with startx). Its log doesn't show any error that I could identify:

On the other hand, Xorg runs as expected using the aarch64 image, glxgears there shows the expected output, that is:
$this->bbcode_second_pass_code('', '
GL_RENDERER = VC4 V3D 2.1
GL_VERSION = 2.1 Mesa 18.3.1
GL_VENDOR = Broadcom
')
I compared the `dmesg | grep vc4` output from the aarch64 image to the armv7h's one I pasted above, and couldn't spot any meaningful difference (omitting said output for brevity). Also compared the Xorg logs, no meaningful difference either up to the point of crash (omitting that log as well).
I also tested the same with Raspbian (current image, so arch armv7l and kernel 4.14.x). Enabling the vc4-kms-v3d driver there, `glxgears -info` reports Gallium vc4 renderer and Broadcom vendor in a manner similar to the aarch64 image.
I tried everything that I could find through our favorite search engines, over and over, and am at a loss about what could be wrong with my config.
I would deeply appreciate any advice or guidance
