There is a similar option available in Percona Server (I don’t recall the exact version, but its in the newer 5.1 build) called innodb_auto_lru_dump. Setting this option will dump the innodb LRU queue to disk at specified intervals (innodb_auto_lru_dump=X, where X is the interval in seconds). On server startup, this file will be read, and the corresponding pages referenced will be loaded into the buffer pool.
