It should still do wake-on-lan, although the fxp driver doesn't support
that right now - it doesn't appear to be a useful feature.
Powersave transitions (D0 -> D3) should also still work. What the fix
does is prevent the board from reducing power in idle state, which is
a subset of D0. (Intel has D0-active and D0-idle, or some such).
