xenodm allows card0 but not card1. /etc/X11/xenodm/GiveConsole
and /etc/X11/xenodm/TakeConsole have the lines
chown $USER:$GROUP /dev/dri/card0
chown $USER:$GROUP /dev/dri/renderD128
chown root:wheel /dev/dri/card0
chown root:wheel /dev/dri/renderD128
Might need to be /dev/dri/card* and /dev/dri/renderD* to allow more
than 1 card. You have 2 cards (drm1 at amdgpu0, drm0 at inteldrm0).
I would "ls -l /dev/dri" to check owners, and try some chown commands
as root, before editing GiveConsole and TakeConsole.
Most OpenBSD users have only 1 card. I don't know whether 2 cards
works on OpenBSD. I can see both cards in your Xorg.0.log,

but Xorg takes only 1 card, then "xrandr --listproviders" has only 1.
This line stood out,
> [ 15.462] (==) Not automatically adding GPU devices
This seems to be Xorg refusing to add more than 1 GPU
(cd /usr/xenocara/xserver && grep -R autoAddGPU). The default seems
to add more GPUs on Linux, and use only 1 GPU on other systems like
OpenBSD, so maybe multiple GPUs only works on Linux.
I guess 2 ways for /etc/X11/xorg.conf to try multiple GPUs on OpenBSD.
These might not work, I don't have xorg.conf on my own systems.
The automatic way would be xorg.conf with no Device sections and
Section "ServerFlags"
Option "AutoAddGPU" "on"
EndSection
The manual way would have no AutoAddGPU and 2 Device sections (1 for
each card). You have it for amdgpu0,

I don't know it for inteldrm0. Your Xorg.0.log had modesetting claim
0@0:2:0, so I guess,
Section "Device"
Identifier "Intel"
Driver "modesetting"
BusID "PCI:0:2:0"
EndSection
(The Identifier doesn't need to be "Intel", but does need to be
different from the other device's Identifier. I don't know whether
the Driver line is needed.)
If either way works, then "xrandr --listproviders" would list both
cards.
