It appears that it is not possible to prepopulate the state name field due to the javascript check that is being made on the field in the checkout form. Is this correct?
The state seems to pre-populate fine for me if it's sent over as either the full name, or the two character abbreviation. <input type="text" name="customer_state" value="TX" />
