Were you able to get it to insert with the bigserial being used on the table?  

Yes.
 
Every time I go to do an insert into one of the inherited tables I am now getting the following exception:
org.hibernate.HibernateException: The database returned no natively generated identity value


Hmm, I guess you are inserting on the parent table not directly into inherited table.
Can you share the INSERT statement.
 
Is auto-increment supported on table partitioning?
 

Yes, BIGSERIAL will create a sequence that will be shared by all child partitions.
Check below example as per your test case, INSERT statement do not have BIGSERIAL column still its auto-increment and populated data in child tables. 

postgres=# insert into mymappingtable(c1,c2,c3,count,createdtime) values (9,20,30,1,now());
INSERT 0 0
postgres=# insert into mymappingtable(c1,c2,c3,count,createdtime) values (7,20,30,1,now());
INSERT 0 0
postgres=# select * from mymappingtablet5;
 id | c1 | c2 | c3 | count |           createdtime
----+----+----+----+-------+----------------------------------
  8 |  9 | 20 | 30 |     1 | 2013-05-18 02:08:33.061548+05:30 

postgres=# select * from mymappingtablet3;
 id | c1 | c2 | c3 | count |           createdtime
----+----+----+----+-------+----------------------------------
  9 |  7 | 20 | 30 |     1 | 2013-05-18 02:12:03.076529+05:30
(1 row)
