I had that problem with my T490 laptop too, but it is fixed now
for me in the latest 13/stable. I think this commit fixed it:
root@thinker:/usr/src/sys/compat/linuxkpi/common/include/linux # git log rbtree.h
commit 9d4303dbe2c4a901418657ed09c9f7096756e8b3
Author: Doug Moore <dougm@FreeBSD.org>

rb_tree: fix stable/13 linux/rbtree.h post ABI fix
Rearranging the left, right, and parent pointers for backward
compatibility with stable/13 in
d8a88ec381498f5942403088d28ee325b92e9a78 is incomplete because it does
not change linux/rbtree.h so that it too knows how rb_left and
rb_right are redefined. So complete it.

I did a "cd /usr/src; git pull --rebase" at Dec 21 08:47 UTC
to update my /usr/src, and that pulled in the above commit.
I then rebuilt and installed the world and kernel with that
sourcecode, then rebooted and rebuilt /usr/ports/graphics/drm-510-kmod/,
(and rebooted again, just to make sure) -- and now I can
kldload i915kms again without problems, and everything works
again. So I am now again on the latest 13/stable, and
everything works.
A big Thank You to Doug and Emmanuel for fixing this, and to
Jonathan for reporting it!
Jeff
