Bug description:
  My system:

  Dell Vostro 1400
  Intel Core 2 Duo @ 2.0 GHz
  3 GB Ram
  1 GB Swap

  I recently got suspend & hibernate working on my system by modifying
  the hal scripts to use acpi-support sleep.sh and hibernate.sh instead
  of powersaved. Now, however, I have found a bug regarding the suspend
  and resume scripts:

  When I resume from a suspend (suspend to ram, in particular),
  /proc/cpuinfo reports that CPU1 is running @ 1994 MHz. Further
  investigation reveals that /sys/devices/system/cpu/cpu1/cpufreq is
  gone entirely (It normally is a symlink to cpu0's cpufreq directory).

  If there's any extra info I can provide, I am more than willing to.
