The replication factor for a keyspace is stored in the
system.schema_keyspaces column family.
Since you can't view this with cli as the server won't start, the only
way to look at it, that i know of is to use the
sstable2json tool on the *.db file for that column family...
So for instance on my machine i do
./sstable2json
/var/lib/cassandra/data/system/schema_keyspaces/system-schema_keyspaces-ia-1-Data.db
and get
{
"7374726573735f6b73": [["durable_writes","true",1968197311980145],
["name","stress_ks",1968197311980145],
["strategy_class","org.apache.cassandra.locator.SimpleStrategy",1968197311980145],
["strategy_options","{\"replication_factor\":\"3\"}",1968197311980145]]
It's likely you don't have a entry from replication_factor.
Theoretically i suppose you could embellish the output, and use
json2sstable to fix it, but I have no experience here, and would get the
blessings of datastax fellas, before proceeding.

Sorry to reply to my own message (again). I took a closer look at the
logs and realized that the partitioner errors aren't what kept the
daemon to stop; those errors are in the logs even before I upgraded.
This one seems to be the culprit.

Cannot load daemon
I'm not sure how to check the replication_factor and/or update it
without using cassandra-cli, which requires the daemon to be running.
