I have just installed the latest stylecop 4.7.7.0 and the latest nightly build of Resharper (build 42) and they work well. Stylecop now has a feature whereby you can override the maximum number of issues reported.
I used an an as-downloaded copy of PowerCollections and increased the limit to 100,000 issues and did a ReScan all with Stylecop. Here are the last 3 lines of the report:
------ StyleCop completed ------
========== Violation Count: 15080 ==========
