Can you try reverting: it's the only think I can spot that might
affect a card that old since most changes in that request were for
display hw you don't have.

    drm/amdgpu: Fix VRAM BO swap issue

    DRM buddy manager allocates the contiguous memory requests in
    a single block or multiple blocks. So for the ttm move operation
    (incase of low vram memory) we should consider all the blocks to
    compute the total memory size which compared with the struct
    ttm_resource num_pages in order to verify that the blocks are
    contiguous for the eviction process.

    v2: Added a Fixes tag
    v3: Rewrite the code to save a bit of calculations and
        variables (Christian)

    Fixes: c9cad937c0c5 ("drm/amdgpu: add drm buddy support to amdgpu")
