'GRANT SELECT ON sysprocesses TO PUBLIC' does not work in SQL 2005

'GRANT SELECT ON sysprocesses TO PUBLIC'
This statement used to work in SQL 7.0 and 2000.
But due to changes in security in SQL 2005 I receive
Server: Msg 4610, Level 16, State 1, Line 1
You can only grant or revoke permissions on objects in the current database.
I am currently on master DB. So I do not understand the error message.
'sysproceses' is a sytem view, in the sys schema.
Objects created in SQL 2005 belong to schemas.
In SQL 2000, sysprocesses is a system table ans objects belong to owner.
Any idea?
