For now, the following workarounds are available:
1) Create a custom User formula field (text) to display the name from the Manager field. Use the syntax: Manager.FirstName & " " & Manager.LastName
This formula field will be available for use in the standard user reports.
2) Create a custom report type for Users. The custom report type will include the standard Manager field for use in reports.
