I must be an idiot, please pity me!

Sure, make another module named db.  Provide a couple functions in db like 
connect and query.

Then in CGI1.py
import db
import mod1
import mod2

db.connect(host, db_name, user, pass)

#do your stuff



And in mod1
import db

def functiona():
        return db.query('SELECT * FROM some_table')


The db module would need to look something like this
#assuming you are using MySQL
import MySQLdb
THE_CURSOR = None

def connect(host, db_name, user, pass):
        global THE_CURSOR
        the_db = MySQL.connect(user=user, passwd=pass, db=db_name,
 hostname=host)
        THE_CURSOR = the_db.cursor()

def query(query_string):
        return THE_CURSOR.execute(query_string)



Of course, that doesn't take into account connecting to multiple database, 
connections sharing, closing the connection, etc...  But it should work for 
what you're trying to do.  If you'd like a more powerful db module, let me 
know and I can share some of the code I've developed over the past couple 
years.
