There are two things that you could verify:

1) That the legacy drm kernel module is also loaded;
2) Since the drm or drmkms use the filesystem (ioctl), the /dev/drm*
also exist.

You can have an overview of drm and drm-kms with the (not included in
the release) manual pages, in the netbsd-xsrc:

./external/mit/libdrm/dist/man/drm.7.rst
./external/mit/libdrm/dist/man/drm-kms.7.rst

Note: I have to finish a modification to userconf and config(1). But
after that I will give a look to legacy i915drm since I have an
integrated Intel GPU too (but I use a discrete radeon, that works in
10.0).
