I've filed a PR for this:
 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245730

I was unable to switch to the drm-fbsd11.2-kmod driver because EDID
failed with it (and I'm not using EFI).

The problem has been documented and is actually fixed in drm-fbsd12.0-kmod:

https://github.com/FreeBSDDesktop/kms-drm/pull/51/commits/5dd56174b9de5d564785c5841b1fc1f309d6e0cd

There's a patch file for the port attached to the PR.

The new xorg-server and its incompatibility with the legacy ati driver
made it necessary to switch to this port.  It's a tremendous
improvement and so thank you to everyone involved in this considerable
and ongoing effort.
