Your config has some problems.  You need to add:
Screen 0
Screen 1
to your device sections to associate the device with a screen.  Also,
the ZaphodHeads option associates outputs with that particular
instance of the driver, so Option     "ZaphodHeads"
"DVI-0,DVI-1" will associate DVI-0 and DVI-1 with one instance of the
driver.  if you want each instance to get one DVI connector, then you
need to do:
Option     "ZaphodHeads"       "DVI-0"
for one device section and:
Option     "ZaphodHeads"       "DVI-1"
for the other section.
