 yes, i think postresume hooks can use config variables.  but this won't
 fix the bug mentioned in set_wake_on_wlan(), because the very short
 wakeups that are the issue don't run the resume hooks.  and in any case,
 the real issue is that the interface simply isn't available yet -- to fix
 this, we need to wait for eth0 to appear before going back to sleep.

 you raise a very good point though.  i'd forgotten about this particular
 race, and it's certainly possible that you're hitting it.  i'll think
 about this some more.  i think i noticed that on 1.75 the wol settings are
 preserved across s/r.  if so, perhaps we can backport that fix to the x86
