What happens if Octavio disables wakeup for that controller before
suspending?

	echo disabled >/sys/bus/pci/devices/0000:00:0b.0/power/wakeup

On kernel 3.2, it lets suspend work again.

For kernel 3.4, I'll break it into two parts: the going asleep and the
wakening back.

For the going asleep part, it works just like 3.2. It previously went
"almost" asleep, but with "echo disabled > wakeup" it suspends correctly.

For the wakening back part, with both settings the PC locks up requiring a
mechanical (power supply switch) power cycle to bring the computer back.
Not even the 5-sec power button cycle helps. I guess this is a different
bug, so I'll try to troubleshoot it and open a different one.
