cat /proc/interrupts may give you what you need, and lspci may help. But I think you can safely assume that it's the kernel module for your ethernet interface that's talking to the hardware. I assume you're seeing these wakeups when you're not using a wired connection? Unloading the module, or disabling it entirely (/etc/modules.conf) may help, then.
