Lo anterior encontrará todas las referencias dentro de cada base de datos, pero no encontrará referencias entre bases de datos. Tomó un poco de juego y el resultado no es precisamente lo que querías, pero creo que lo hace más claro:

DECLARE @table_name SYSNAME = N'%'; -- find all



CREATE TABLE #d
(
    db SYSNAME, 
    [object_id] INT, 
    sch SYSNAME,
    obj SYSNAME,
    ref_db NVARCHAR(128),
    ref_sch NVARCHAR(128), 
    ref_obj NVARCHAR(128),
    ref_object_id INT,
    type_desc SYSNAME
);

DECLARE @sql NVARCHAR(MAX) = N'';

SELECT @sql += 'SELECT ''' + QUOTENAME(name) + ''',
    d.referencing_id,
    QUOTENAME(s.name),
    QUOTENAME(o.name),
    QUOTENAME(d.referenced_database_name),
    QUOTENAME(d.referenced_schema_name),
    QUOTENAME(d.referenced_entity_name),
    d.referenced_id,
    o.type_desc
FROM ' + QUOTENAME(name)

INNER JOIN ' + QUOTENAME(name)

    ON d.referencing_id = o.[object_id]
INNER JOIN '

    ON o.[schema_id] = s.[schema_id]
WHERE d.referenced_entity_name LIKE ''' + @table_name + '''
UNION ALL

FROM sys.databases WHERE database_id BETWEEN 5 AND 32766;

SET @sql = LEFT(@sql, LEN(@sql)-11);

INSERT #d EXEC sp_executesql @sql;
