Thanks Andrew, I'm quite sure I have the bumblebee-disablecard and
bumblebee-enablecard files configured correctly. I don't get any errors just
the integer output, which according to the acpi_call README should be good.
There is no difference in battery use however. It is still exactly the same.

What I don't know is why there are two lines to turn off:
echo NVOP $(acpi_call "\_SB.PCI0.LPC.EC.PUBS._OFF 0 0x100 0x1A
{255,255,255,255}")
echo _PS3 $(acpi_call "\_SB.PCI0.LPC.EC.PUBS._OFF")

What does NVOP and _PS3 mean?
Shouldn't something else/more be added to turn off the card completely? I've
found a discussion somewhere about using setpci, however I too much a noob
to get what it is about :(

It feels like we're pretty close, the nvidia card is just not going to
sleep/shut down.
