2 watts _less_? If anything, I'd have expected that figure to be higher with ACPI disabled. Seems like something is weird then. One way to debug excessive interrupt issues might be to instrument the interrupt handler in the driver to analyze the exact type of interrupt that occurs for a particular device.
