If you add a Freedom Pass to an Oyster online account the expiry shows
as 2010.

I don't suppose you can add pre-pay to them now can you? (for those who want to travel before 9am)

When you present a Freedom Pass at a touchscreen ticket machine the balance is
given as £0.00 but the option to add prepay is not there. However, if you add
the Freedom Pass to an online Oyster account the balance is given as well as the
option to add prepay and auto top-up. Don't know what would happen if you try
it out.

I've emailed ALG (who run Freedom Pass) on behalf of one of my parents who
gets confused holding two cards. They emailed back and said they plan to add
prepay soon-ish but there are some obstacles:

1. Some early freedom passes cannot handle prepay.
2. There needs to be some admin set up as there will effectively be two suppliers
for each Freedom Pass. ALG for the "travelcard" element and TfL for the prepay.
3. Travel on a Freedom Pass is an entitlement so the normal practice of blocking
travelcard use with a negative prepay balance will have to stopped.
4. This slightly complicated arrangement needs to be effictively communicated.
