Ok, I do not consider this to be a regression. 

Clearly UPX is expecting a very specific kernel format, and clearly UPX 
just needs to be updated for the changes.

That said, if some UPX person can explain what it is that UPX needs, maybe 
we can add some format markers into the kernel (and perhaps some extra 
header info) so that future format changes are transparent or at least 
break in obvious ways.
