I've been using DPM in my rv635 for a few days now (intensive use, as this is my main machine) and had no issues yet. I can however, still tempt fate and try some nasty things such as quick zoom in/out cycles in big .svg files in inkscape, and see if that causes issues. I know it used to a long time ago.
If you do run into a problem make sure it's specific to dpm. If you had a particular problem in the past and you get it again, it's probably not dpm related.
