SharePoint 2010 Management Shell and Windows Management Framework 3.0

I have four Windows Server 2008 R2 machines which are used for SharePoint 2010.  However, I remotely connect to these machines from my Windows Server 2012 box.  Windows Server 2012 has a pretty nifty Server Manager which allows management of remote servers, but in order to manage Windows Server 2008 machines, it needs Windows Management Framework (WMF) 3.0 installed on the 2008 machines.

I've installed that, and can manage the servers remotely - works brilliantly.  However, opening the SharePoint 2010 Management Shell (PowerShell) now produces the old favourite error message:

The local farm is not accessible. Cmdlets with FeatureDependencyId are not registered

I've found (from this post on TechNet) that WMF 3.0 seems to be a bit incompatible with SharePoint 2010. A blog post - Henrik's blog: SharePoint 2010 - Windows update powershell error - recommended uninstalling WMF 3.0 to resolve this.  But I found that adding a '-v 2' parameter to the shortcut for SP2010 Management Shell seems to work quite well so far:

C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe -v 2 -NoExit  " & ' C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\POWERSHELL\Registration\\sharepoint.ps1 ' "

There are some reports that this doesn't completely fix the incompatibility, but I've not encountered any other problems yet.
