uupdate typically doesn't care at all what the extract folder name is...

The following diff against upstream debian folder allowed me to do a  
dirty build of an optimized (with asm enabled) version of xvidcore on  
amd64 pbuilder:

Also, you might want to check with debian-multimedia.org, we have  
xvidcore packages there, although not up to date (yet) either, AFAICT:
