I'm slowly trying to work on this, but if someone who knows what they are 
doing wants to just get it done, feel free.

The commit that breaks things was developed on an old enough kernel that 
it was a problem with the compat stuff being out of sync. I'm trying various 
merge points to try to find a good place to test if there is a separate 
problem or if my change for that one is bad. The builds take a while so 
this hasn't been happening quickly.
