I don't boot my laptop with any external display plugged in.

Ok, but you say that I can't use the second (preferred) option when I load the
nouveau driver - so I must use pcie_port_pm=off. Shouldn't the nouveau driver
be updated to support the second option in stead?

Not so, I am already on kernel 4.9.34:
tux_xc1706 ~ # uname -a
