It's not possible, at least in the current implementation of ohci1394
and firewire-ohci.  All interrupt events are disabled and the link layer
controller is powered down when the machine enters suspended mode.  I
don't know if it is possible for PCI drivers to leave interrupts and
receive DMA contexts etc. enabled and wake the machine up when an
interrupt event occurs.

Does wake-on-LAN (Ethernet) and wake-on-USB work by means of special
hardware support?
