  from the description you give, the process looks very similar to what
  i did for my Dell Latitude X1, similar features except for a 12.1" screen,
  no fingerprint, and intel2200 instead of atheros card.
  The output of pciconf -lv is attached.

  suspend/resume does not work well. actually, one issue is that
  the screen goes off when you close the lid and even though the
  rest of the system seems to be somwehat alive, i cannot see
  anything.

One trick I have found was hw.acpi.reset_video=0 and turn on 
a bios boot password.  When the laptop resumes, the bios seems
to do a better job of reinitializing the screen.
If I use reset_video, I get an instant reboot.
If I do not, I get no video (I believe).

I have a Dell D810, and similar to my previous Inspiron Pentium-M,
It seems that I can suspend and resume but it never stays asleep.
The system ALWAYS wakes up within 1-10 seconds (the D810 takes longer
before it decides to wake back up).
