Well this is a Mac OS X only project and you do work for Apple and Apple sure used to include plenty of patches to the included ssh build for 10.5.x (see <
http://www.opensource.apple.com/source/OpenSSH/OpenSSH-95.1.5/patches/> for example) -- and it looks like they're still there in the 10.6.x version, except neither the .orig files nor the patches directory is present anymore.
Any chance you could send the appropriate ssh patch along to the internal Apple folks in charge of ssh? (I'd guess Disco Vince Giffin can point you in the correct direction if he's not handling the patches anymore.)
The
openssh-unix-dev@mindrot.org mailing list is also quite responsive to applying ssh patches -- someone (usually Damien Miller) generally applies reasonable looking patches promptly.
