Q:

Load a model with not autoincremental id

I have created a model that uses unique string as ID field, no issue for saving it after setting  protected  $_isPkAutoIncrement = false; in Mysql4 resource however I'm facing an issue when I try to load it:
->load('mystrinid') return me this error:
Invalid method MY_MODULE_Model_Mymodel::load(Array
(
    [0] => mystrinid
)

UPDATE:
this is working

A:

Both Mage_Core_Model_Abstract (the model) and Mage_Core_Model_Resource_Db_Abstract / Mage_Core_Model_Mysql4_Abstract (resource model) define load(), so there's something amiss with your class inheritance.
