The installer no longer detects an MBT device and adds the expected loader.conf.local file and values.

The required kernel modules to drive the hotplug HDMI port are not present to be loaded anyway. i915kms drm2

It looks like a patch has been lost in the rebase.

It looks like the i915kms driver has been removed from the kernel in main (14) so that's why we don't have the module any more.
We can instead install the drm-510-kmod port, which now contains this driver. I'll post patches to add this to amd64 images soon.

The lack of the expected loader variables is probably due to the missing factory script. (See
Brad merged improvement to the installer to make this all easier to maintain, but hasn't yet migrated all of the factory script customisation.

Those should ensure the driver is installed, but won't fix the missing loader variables. I'll coordinate with Brad about that.

This should be fixed as of 5667935a3058064442fc16363f825dfc4bce0c90.

I don't have the hardware to test this myself though, so it'd be appreciated if someone could test tomorrow's snapshot.

No video output after hotplug HDMI

I assume the either zfs or hotplug driver issue remains?
I remember there was a boot issue, which is why I decided to keep this disabled, and opt for zfs instead; a permanently attached screen (or an extra reboot) is a small price to pay to have zfs...
