-current and 13.2 boot and run on Alder Lake, and probably Raptor Lake (I

It works with drm-515-kmod, but I have been unable to get VA-API or DRM to
work much. driinfo reports swrast. Performance is pretty bad compared to my
12 year old Ivy Lake, but surprisingly fast with all 12 threads on my
ThinkPad T16 running. a 1180p video runs at about 13% of the total CPU
capacity. glxgears get a rather paltry 900 FPS. But everything seems to
work.
