This is totally fucked up code, but if you like hazard...
I mean that I really just called some random ACPI (aml) methods
not knowing what they should do.
Additionally this code is for my laptop. I have GEFORCE 620M
GPU, so I added this to pcidevs. Another thing is that patched
code recognizes my GPU device through ACPI name
"\\_SB_.PCI0.PEG0.PEGP". I have discovered name when I was
using Linux kernel's module called acpi_call. Other laptops
may have differently named GPUs.
