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?
