What version are you talking about?  GRANT and REVOKE seem to be 
replicated fine nowadays.  I remember some bugs related to their 
replication, but they were about replicating them when they 
shouldn't be (when the mysql DB wasn't being replicated), not 
failing to replicate them when they should be.  Also FLUSH 
PRIVILEGES is replicated as of version 4.1.1, according to the 

The original poster might want to look into the read-only option 
to prevent accidental modification of the slave data:
