(replying to all in order to reach Simon, too).

Latest releases of openssh (not yet in FreeBSD, but already in Arch I 
guess) disable ssh-rsa signatures. IIRC, there should be a way to 
re-enable them in the config, but a cursory search found nothing, so 
maybe I'm remembering poorly.
The best way forward would be updating all the involved keys, but - 
again IIRC - darcs hub uses an Haskell implementation of the ssh server, 
so it could be not so straightforward.

Ciao,
Gian Piero.

PS: anyway, while at it could it be possible to also implement support 
for ed25519 keys?.
