Out of sync error with Intel 945G when exiting X

When I exit X (xorg-x11 7.1), instead of being returned to the command
line, my monitor reports an 'input out of sync' error.  The horizontal
rate reported is 70.1 KHz (my monitor supports 30 - 83). while the
vertical rate is 87 (my monitor only supports 50 - 76).  I am not sure
why it is being set to this upon exiting.

I have also noticed the same behavior when I try to switch to one of
the text-only consoles (Ctrl-Alt 1 - 4) while X is running.  Can
someone point me to the culprit, or at least to where I can find a
clue of how to solve this?  At the moment, when I've exited X, I can
type at the command line, but can't see anything, so I can reboot,
which "fixes" the problem until I run X again.

I have an Intel 945G/GZ integrated card, on an HP A1530N desktop with
a Pentium D 2.8 GHz processor.  From searching around, I've read that
this is likely something to do with what state the video BIOS reports
to the Intel driver to use, but none described this problem, only a
problem with getting X working in the first place.  I am not sure why
it cannot return to the same state it held before starting X.

Part of my xorg.conf file is as follows:
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "HP"
        ModelName    "HP vs17e"
        HorizSync       30.0 - 83.0

        Option  "DRI"   "True"

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes   "1280x1024 at 60"

I get this at the end of my Xorg.0.log file:
(--) Mouse0: PnP-detected protocol: "ExplorerPS/2"
(II) Mouse0: ps2EnableDataReporting: succeeded
(WW) I810(0): Successfully set original devices

FreeFontPath: FPE "/usr/share/fonts/misc/" refcount is 2, should be 1; fixing.

Any help would be appreciated.  Thanks!
