This is just a guess, but you should remove ath_hal, wlan and ath_pci.
You are only removing ath_pci.  If you don't remove ath_hal, during
sleep/resume it could become unstable.  Since it is a prerequisite for
ath_pci, when you try to start ath_pci it hangs waiting for ath_hal.
Also, why use rmmod instead of modprobe -r?  Since you're inserting with
modprobe makes sense to remove with modprobe for consistency, also
modprobe takes care of dependencies and options.
So, I would do this:
/etc/acpi/sleep:

  #! /bin/sh
  /etc/init.d/hotplug stop
  ifdown ath0
  modprobe -r ath_pci
  modprobe -r ath_hal
  modprobe -r wlan
  sync
  echo 3 > /proc/acpi/sleep
  #/etc/init.d/hotplug start
  modprobe wlan
  modprobe ath_hal
  modprobe ath_pci
  ifup ath0

Let me know if this works!
