Yes.

The LOMlite has poweroff function but not via powerfail interrupt.

And nothing happens when I press the power button if the powerfail
interrupt is enabled. But if it is disabled, kernel outputs the
message as below.

        interrupt_vector: spurious vector 7de at pil 0

Similar message is showen on Solaris as below.

        WARNING: invalid vector intr: number 0x7de, pil 0x0

So Netra X1 has some sort of other interrupt, but I couldn't find
out the details. I think "power at ebus" is suspicious.
