I can confirm the BSOD workaround.

I was investigating the DSDT from /proc/acpi/dsdt

I booted with nvidia and intel and dumped/decoded the DSDT and running diff i get

< OperationRegion (MBOX, SystemMemory, 0xBFDBEC18, 0x000002BC)

There is only two changes...

I created/compiles a DSDT to reflect the nvidia version and added via update-initramfs rebooted but there was no change, Card will not activate via this method (for me)
