Whoops, I spoke too soon!  The RS780G chipset really is SB700 
southbridge (device id 0x4391), and the kernel detects it just fine. 
What happens is EDD returns the wrong disk geometry when I boot the Zino 
HD from a Kingston DataTraveler USB flash drive.  But it returns the 
correct geometry when booted from a Corsair flash drive.

This problem was mentioned by ablyons on Trac: 
https://sourceforge.net/apps/trac/unattended/ticket/1

So my patch was totally the wrong direction, whoohoo!
