i don't think your site is being penalized at all. i have lots of experience with this sort of matter. Every 3 or 4 mos. google does a major "refresh" or update of the serps. Pages w/o a high PR are very likely to drop dramatically as a result of the update in favor of sites with either a higher pr or pages that are simply newer in nature. Google has a real fondness for "new information". Even though your home page is a pr5, it is likely that the subpages don't have a pr that is high enough to maintain their position in the serps. It is just one of the many games that google plays to drive people crazy and thus to adwords.
