I don't know if you can't use ODBC, but that's what I'm using now to
access an Access database. A (maybe) useful snippet:

import dbi, odbc # The order of this import is important!
connection = odbc.odbc('Driver={Microsoft Access Driver (*.mdb)};' +
                       'Dbq=C:\database.mdb;Uid=Admin;Pwd=;')
cursor = connection.cursor()
cursor.execute('SELECT column1, column2, COUNT(*) FROM table' +
               'WHERE column1 < column2' +
               'GROUP BY column1, column2')
print cursor.fetchall()

AFAIK, the main advantage is that it is easier to change to another
database later if needed, as the odbc module uses the same interface as
many others.

At least in my application, it has the same performance as Access itself
(most of my queries return just some sums and groups, none of them
return big chunks of data, so most part of the processing is kept on the
Jet side).

Hope that helps,
Felipe.
