WRT the example mentioned earlier, our activity occurs on subdomains, but the PR is visible on the main domain (which is just a splash page).

For example, we use

CMSworkarea.example.com/examplepage/section/

for internal purposes related to development of other sites. If you visit

example.com

you see a simple splash page saying that example.com is parked, or under construction, or whatever.

There are no links going to example.com or any of its subdomains, yet the Google toolbar shows it as PR 5.
