I'd say i915.ko is not supposed to be loaded by the loader, only afterwards. On FreeBSD it is the same (I vaguely remember there are technical reasons for this)

https://wiki.freebsd.org/Graphics says to load the module after the kernel is loaded by adding the module to kld_list in /etc/rc.comf which would become something like i915_load=YES in DragonFlyBSD.

When I tried last time to load i915, it paniced somewhere in the kernel linker, so I am assuming it's somehow related to that.

to clarify, I am talking here about the ELF loader at boot time: src/stand/boot/common/*_elf64.c. IIRC, loading i915 on FreeBSD (14) succeeded, and I've seen some updates on their boot-time ELF loader. Bringing these changes to DragonFly might fix that problem.
