If I boot with acpi=off, the hotkeys work. I can see the keypress by
watch'ing /dev/nvram. But with acpi, the keys dont work and nothing is
registered in /dev/nvram when any of the hotkeys are pressed. 

However the power button is recognized by acpi and I can use it to shut
down properly.

Here is the /proc/interrupts
