Auto_increment generated id as the Partioning Key

Are there any limitations with respect to tables using an auto_increment generated id as the partioning key? I am running into some problems with MySQL 5.1.7-beta on Linux with partitioned tables that seems to be related to the auto increment.

First of all when I try to drop a partition that I am no longer writing data to, while writing data to another partition, MySQL seems to delete data in all partitions. As new records are written to another partition, the auto generated ids are 1, 257, 65793, 16843009, 4311810305, 1.10382E+12, 2.82579E+14 respectively. The subsequent insert fails with a range error for the datatype. Seems like the values are being incremented to the maximum value for various integer data types.

Any insight is appreciated.
