IIRC, sometimes the method is hung off the other GPU.

Looks like it works fine without the patch as well. That said, the ATRM patch

ATRM is an acpi method for fetching the rom on certain systems. If your system
was able to fetch the rom via another method, it may not use ATRM.
I'm not sure if the ATRM method is required in drill87's case

I guess it fixes. At least, I can see no errors for radeon module in dmesg.
Vgaswitcheroo, as I aforementioned, works too (I can turn off the card, so
notebook heats less).
However, I cannot say any
