Well this is a PCI bus / BIOS / Linux pci subsystem problem.

If this is the proprietary nvidia driver, good luck with ever resolving
the problem.

Some things do stand out as odd.

One of course doesn't want a Base Address Register (BAR) to be
0x00000000.  And if that's the case, the BIOS or the linux PCI subsystem
filled it out that BAR wrong or deliberately set it to 0 because it
couldn't find a large enough memory window for the NVIDIA device.

However, the module probed 0000:01:00.0, but the error messages gripe is
against PCI:0000:00.1  which I'm not sure exactly correspond.

Could you provide

1. the output of  lspci -nnvv 
2. the e820 memory region information from the dmesg
3. the output of  cat /proc/iomem
4. the output of  cat /proc/meminfo


I suspect the problem is simply something about no contiguos memory
window being available.
