Tried that, patch still doesn't apply... and I just figured out why. Looks like my email client is screwing the patch up. mutt apparently wants to chew on my mail before I get it. viewing the mail as an attachment and saving it works properly however.
Now that I have properly saved the mail, it applies cleanly to tip/master as well as 74f5187ac873042f502227701ed1727e7c5fbfa9 - though in the latter's case it's having to fuzz around a bit. I'll try testing 74f5187ac873042f502227701ed1727e7c5fbfa9 first since it's the one I *know* is flawed, and I want to reduce the amount of changes that I have to test for.
I'll build and test it, then let you guys know if there's any noticable difference.
