I started Percona Server 5.5.27-29.0 without flashcache, but what I see is:
mysql> show status like '%flashcache%';
+--------------------+-------+
| Variable_name | Value |

| Flashcache_enabled | OFF |

1 row in set (0.00 sec)
mysql> show variables like '%flashcache%';

| have_flashcache | YES |

1 row in set (0.00 sec)
