There isn't a very clean way way of doing this. Your best bet will probably be to use AccessEnum from the Microsoft Sysinternals Team.
You can point the program at a location on your machine (eg. C:) and it will show you all the permissions for all files and folders. You could then dump this to a CSV and analyse in Excel.
There's a third party tool called Enterprise Permission Reporter that I use that's pretty easy to use and the output is fairly contained so you don't have pages and pages to sift through. It displays the permissions per folder, per user (so to speak). It might not be as comprehensive as you need but you can give it a try. The demo version is limited to 25 directories, but it should give you a feel for whether or not it gives you what you need.
There is a program I found that is nicer and free. NTFS Permissions Reporter by CJWDEV [ http://www.cjwdev.co.uk/ ] The free edition is limited in output of type files, but you can export to HTML and then import the HTML file into Excel for manipulation. I have the program to be useful. -Ron Maagero
PS. I understand the question was asked in 2009, but I figured an updated/different wouldn't hurt.

There's a script to enumerate ACLs here, but I haven't tested it personally.
