Yes.  By default it will store its quirks in
/var/cache/pm-utils/last_known_working.quirkdb (source: man pm-utils)

Also, from /usr/share/doc/pm-utils/README.debugging:

* If a parameter (or lack thereof) passed to pm-suspend and friends is causing
  problems, or you need to debug the suspend/resume process to work out what 
  quirks are causing problems, you can use the ADD_PARAMETERS and 
  DROP_PARAMETERS environment variables.  To do this, create a file in 
  /etc/pm/config.d, and add the following lines to it:
  ADD_PARAMETERS="--parameter-to-add --another-parameter"
  DROP_PARAMETERS="--parameter-to-drop --another-parameter-to-drop"

  If you want to drop all parameters (for testing purposes, or to work around 
  bugs in HAL), you can use DROP_PARAMETERS="all"
