Don't blame Alan, it was probably me. I've been working on TCP issues, but I have only fast interfaces to play with (loopback and normal ethenet, soon fast ethernet). Those two are faster these days, but it could have impacted slow interfaces negatively (I don't see how, right now, but I might be missing something).
How isolated have you gotten it? Can you check if it's the tcp.c or tcp_input.c changes? (if it's the retransmit changes, _then_ you can blame Alan ;-)
