For #5 as you mentioned, there was a patch upstream that fixed it. It was addressed in Bug 3936: https://bugzilla.yoctoproject.org/show_bug.cgi?id=3936. Here's a link to the upstream patch: https://lkml.org/lkml/2013/1/16/297 This was supposedly merged in. I'll track the commit down tomorrow. I'll look into steps #1,#2,#3 tomorrow as well.
