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?
