Yes, I understood. Here are some more details on why my first
reaction was negative:
o Most of the time the system can boot anyway and we get lspci -v output,
  /proc/iomem, etc. If that's not true, then other parts of the kernel
  need to be more robust (e.g. drivers crashing because resources aren't
  assigned.

o Bringing up linux on a new platform is NOT something we've generally
  had to do via email. Usually someone with kernel/IO experience is
  involved and can build new kernels.

Sorry, I misread the patch.
I was thinking of "pci_early_dump" as a seperate option but
either "pci=" option is fine.
