    Ok, so it didn't use to be at the 4GB mark.

    This seems to be a PCI and resource alloc issue. It would be really
    interesting to see where the 4GB allocation started. Ie ignore anything
    else (warnings, driver loadings etc), and _just_ look at lspci -vv output
    for where the memory got allocated.

    Did you already bisect that and I just missed it?
