To get the PR passed through a link divide the PR of the linking page by the number of links on that page.
So if a PR6 page has 10 links on it then each link is getting PR6/10.
Now, Google's toolbar scale is not linear, it is on a curve. The base, according to my experiments, is roughly a 5. So a PR2 is 5x harder to get than a PR1, and a PR3 is 25x harder to get than a PR1, and a PR 4 is 125x harder to get than a PR1, and a PR5 is 600x harder to get than a PR1, and a PR6 is 3000x harder to get than a PR1, and a PR7 is 15000x harder to get than a PR1, etc etc etc.
Also, the scale is very general, there could be a huge difference between a low 5 and a high 5 but they'll both be shown as 5.
