Grr. Argh. I suck. Its NOT working. :(

I stupidly had both an rpm install and source install on the box. The source 
install was a sufficiently old svn trunk build that looked much more like 
0.20 than current svn trunk, so I stupidly didn't notice that's what I was 
scanning with, not the 0.20-fixes build. However, I've got an actual working 
build together now. MUCH bigger changeset and far messier, but hey, at least 
it works now... Will work on getting that in tomorrow, too exhausted right 
now.

Heh, you think that was something... My working local build basically 
backports everything from ~11682 to 11702... :)

(Still want to see what I can possibly omit, and freebox support could be 
broken by my changes).

Hrm... basically just took the relevant trunk changesets I happened upon and 
threw them in. Can you point me to what I missed? Wouldn't mind adding that 
to the mix.
