Intellij IDEA (9.0.1) cvs appears to not be honoring file permissions?

I'm on IDEA 9.0.1 (Build #IU-93.94) which is perhaps a version or so behind, but enough up to date such that I would think the cvs bits would be working properly...

There is a script that someone checked into our cvs server.
When I check it out from the command line, the permissions are set correctly, with the executable bits on (755).  However, when I update through IDEA, it pops out as not executable (644).

Does anyone have any idea how to make idea behave correctly for scripts that are checked into cvs?
