Sounds like there's something weird going on:

[    1.862577] pci 0000:01:00.0: BAR 6: no space for [mem size 0x00010000 pref]
[    1.862592] pci 0000:01:00.0: BAR 6: failed to assign [mem size 0x00010000
pref]

So ... question 1: did this ever work, with any kernel?

I'll be honest - I've never actually tried a NV4 (no AGP motherboard here).
Last I tried a NV5 (PCI version), it worked fine. This was some time ago, and I
can re-check if necessary. However:

[  103.927615] nouveau 0000:01:00.0: pci: failed to acquire agp

is definitely worrying. From the kernel messages, it would appear that the
agpgart support module is loading *after* nouveau. This is not good. Try
compiling nouveau as a module, and ensuring that it loads after the agpgart
module.

Of course, I don't know that this is highly related to the issue at hand -- AGP
is for the GPU accessing system memory, which is not necessary to retrieve the
VBIOS data.

Please try booting the 4.x kernel with

nouveau.debug=bios=debug

which might yield more info. Please don't use NvBios=PRAMIN when doing this,
and include the full boot log.

You can also use nvagetbios from envytools to fetch using certain methods
(definitely the ones applicable to your hw).
