Oh darn, I missed the importance and relevance of that e-mail (but I did get it),
which might have saved me a lot of time.
It sounds like it is exactly the same issue.
I'll try it as soon as I can either resolve the conflicts, or go back
and apply it to whatever kernel version would result in no conflicts.
I'll report back once I have some test results.
