dmesg with nouveau.debug=trace + acpidump + xorg.conf

I've got a portable computer with an Intel graphic card and a nvidia discrete
card (G 105M).
I've installed Fedora 26. 
Everything should run fine with nouveau and Prime.

However, xrandr --listproviders only send me 1 provider, which is the Intel
card. 

I've seen a problem with the BIOS and the nvidia card : 

[    2.777871] nouveau 0000:01:00.0: Invalid PCI ROM header signature:
expecting 0xaa55, got 0x0000

--- Comment #1 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
The issue is that shadow_fetch() fails for ACPI. It tries to read a
0xf800-sized image and apparently can't. Both the fast and slow methods end up
the same. Also it's NPDE is set to "HYB$", although looking at the code that
shouldn't really matter.

However something's there, since it gets far enough to e.g. check the NPDE.
Either the _ROM method is buggy, or we're driving it slightly incorrectly.
