Windows 2008, PowerShell 2.0 isn't able to load FailoverClusters module, says no valid module file was found

Hi all.

On our Windows 2008 SP1 Server running a Windows Cluster (not R2) I've installed PowerShell 2 (KB968930) but when I attempt to run this:

Import-Module FailoverClusters

It says the module couldn't be loaded because no valid module file was found in any module directory. I've ran this as both myself (I'm in Admin group) and as the local administrator with the same results.  When I run Get-Module -listavailable it only lists BitsTransfer and PSDiagnostics.  

This server is one of the nodes on the Windows Cluster and the Windows Cluster service is running with the cluster being up and working without issue.  So how can I get the FailoverClusters module available in PowerShell?

Thanks.
