Basically thats what happened. Microsoft somewhat acknowledged it http://support.microsoft.com/kb/945977

They basically implemented a new feature in SP2 and enabled it by default weather your hardware supported it or not and it affected many servers, not just the few specifics they list here.

BTW for those who never had an issue with MSOffice. I finished a spreadsheet in Excel 2010 and saved it, hibernated my work laptop, went home and resumed and connected to the vpn and dialed into a late meeting and Excel could not find my spreadsheet. A search finds the shortcut in the recent documents to it but it didn't exist. So I looked unprepared for my meeting and and to do my work again afterward.
