There's nothing strange about it, at least none that I can see.
You can see in the attached dmesg output that it worked fine.
The X output says it saw a kernel module, but it didn't like the version.
The next time it starts, it sees something it likes.
This message:
[ 135.892] (II) [KMS] drm report modesetting isn't supported.
is produced by:
ret = drmCheckModesettingSupported(busIdString);
I googled that and found:
