There has been at least one fork that reversed bitcoin transactions. They are in no way final in practice even if the "spec" claims that they are.

The resulting fork isn't Bitcoin, though, so no Bitcoin transactions are reversed in this manner.

Actually the non-bitcoin fork is the one that didn't reverse the transactions. Bitcoin proper is the one that did reverse them if memory serves. I'll grant that sometimes memory does not serve though and I'm just too lazy to grab the citation right now.

I think you're thinking about this incident? https://en.bitcoin.it/wiki/Value_overflow_incident
In that case, ~9 hours of transaction history were reversed because of a transaction that resulted in an overflow in the main (and I think only at the time) Bitcoin client allowing the creation of unlimited Bitcoin.
