[CentOS] Strange behavior in X, esp. VMWare Windows

Last Thursday, for some reason (possibly a power failure), my work
desktop had a different video configuration than when I left Wednesday
evening.  I have two 17" flat panels configured as a two-head wide
(side-by-side) single display.  When I arrived on Thu, I had two
individual desktops instead, the resolution was down to 800x600, and
so on.  The monitor type had been reset to generic 800x600, and the
vido card was unknown.  (This was not true before.)

After a lot of fooling around with the xorg.conf file, I finally got
it back to where it should be, for the most part.  My current
xorg.conf is included below.

The problem is that I typically run certain apps on the right screen,
including seamonkey and Windows under VMWare workstation, and since
the new configuration came in, the mouse cursor is not where it should
be.  Items light up when I run the mouse over them, but a little below
and to the right of the tip of the pointer.  It is only a slight
dislocation, but significantly worse in the Windows on VMWare, and it
is really annoying when I have to mis-aim the cursor to hit certain
selections (check boxes, bullets, etc.).

Can anyone explain this?  Here's my xorg.conf:

# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:

#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"

# If you'd like to switch the positions of your capslock and
