We've been able to successfully use CruiseControl.NET and MSBuild to automate installations on local machines and servers of DNN 4.4.1.  However, when we call the Install.aspx page with mode=Install and mode=InstallResources, it says that it installs modules that are in the Install/modules folder, but they don't appear anywhere afterwards.  The ZIP files aren't even there any more.  And, there are no assemblies in the bin folder, no module folders under DesktopModules, nothing...  The ZIP files are proper PA ZIP files as if I go and manually install them, they work just fine.  Is there something wrong with the Install page?  Funny thing is that we also install a skin via this process and that works just fine.  This is basically the last step that we have to work through and we're golden!  Any help is appreciated.

Some of my findings for everyone's benefit...

It seems that there are several validations that occur when a module is installed.  When you use the Install.aspx?mode=InstallResources page, even if those validations fail, it still reports the module as successfully being installed and I cannot find where it logs any of the validations failing.  In the case of some of our failing modules, there were dependencies that were missing (i.e. ASP.NET AJAX and the AJAX Control Toolkit) from the bin folder or the GAC, since it tries to instantiate dependencies via reflection as a validation that everything is there for the module to work.  I think the bug here is that it does not report these problems when using the Install.aspx page and just says Success.  Once I figured out the dependencies that were needed (through debugging of the DNN Install.aspx page), the modules installed correctly and were available for selection immediately.
