PEBKAC.

I had configured the kernel to restrict DRM to 1920x1080:

options                DRM_MAX_RESOLUTION_HORIZONTAL=1920      # Limit DRM size in horizontal dimension
options                DRM_MAX_RESOLUTION_VERTICAL=1080        # Limit DRM size in vertical dimension

because otherwise my previous graphics card wasn't working.  Not too
surprisingly, this feature works and limited the resolution. I've
removed these two lines, now I get 4k in the framebuffer and in X.

Yay!
