It looks like my problem was that 'Virtual' in the "Display"
SubSection of the "Screen" Section has quietly become mandatory to
support multi-monitor configurations.  With Xorg 7.4, I had no
'Virtual' size specified and everything worked as expected.  The same
configuration in Xorg 7.5 causes corruption of the display on the
second monitor, whether it is located to the right of or below the
primary monitor.

Including an appropriate 'Virtual' in each "Display" SubSection has
resolved the corruption issue.  Note that, although the config file
parser allows 'Virtual' in the "Screen" Section, it has no effect
there - this appears to be a bug in hw/xfree86/common/xf86Config.c
that was introduced in xserver 1.6.
