I'm afraid I spoke too soon :(

On FreeBSD 13.0-RELEASE, resuming from sleep is behaving the way it did around
13.0-RC2/RC3 for me. This is, it works most of the time, but still fails once
in a while. Unlike 12.2-RELEASE, where it just works all of the time...

Anyway, I discovered that when I get the dreaded "drmn0: Failed to idle
engines, declaring wedged!" message, I can:

kldunload i915kms; kldload i915kms; service sddm restart

to get back X, at the cost of losing all my unsaved open files and stuff. At
least this way I avoid having to reboot my system.
