vbios.rom

I have a VAIO SVS1511C5E laptop and the nouveau driver is not working in kernel
versions > 3.16 . (3.19 does not work for me)

>From my understanding the ACPI loading of the bios rom fails. I tried other
methods as suggested in many other threads (PROM, PRAMIN), but they also fail.
ACPI loading worked in kernel 3.16.

I attach the vbios.rom copied from a booted 3.16 kernel from
/sys/kernel/debug/dri/1/vbios.rom and a dmesg log showing the error from kernel
4.10rc3.

As a workaround I am able to load nouveau manually in all kernels by providing
the copied vbios.rom as a parameter to the nouveau module.</pre>
