When Unigine Sanctuary is started with RADEON_HYPERZ=1 it asserts almost immediately. This is with all graphic settings set to lowest possible.

    r300g: derive user buffer sizes at draw time
    
    This only uploads the [min_index, max_index] range instead of [0, userbuf si
    which greatly speeds up user buffer uploads.
    
    This is also a prerequisite for atomizing vertex arrays in st/mesa.

BTW I had to also manually apply 96d8a54716d96bd28f0c54a25ca6904fb4321a55, I suppose it doesn't change anything
