What can I do now?

No idea. It looks like the log file says 1600x1200 is a valid mode.
I don't see it saying any reason why it won't use it. Maybe
someone more familiar with the log output generated by the
intel driver has an idea?

Do you have an /etc/X11/xorg.conf file that explicitly mentions
1280x1024? Maybe just renaming the xorg.conf file would make
things work?

The xrandr command says that it cannot "see" beyond
1280x1024.  I am assuming this is a problem?

Here is my xorg.conf file as generated by system-conf-display:
======================================
# Xorg configuration created by system-config-display

        Modes    "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection "Display"
        Depth     16
        Modes    "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection "Display"
        Depth     24

    EndSubSection
EndSection
===========================================
Note: Adding "1600x1200" to Depth 24 does not help
at all.

Again, please note that xorg works on F8/9, not F10,
not F11, so perhaps there is a major change since F9?

I also posted to the Xorg Users and may be forced to
file a bug if there is no resolution.  I just wanted to
check with others who might be having problems
but that would mean they would have to have a
CM715 monitor or similar, as nowadays this is an
ancient monitor compared to all of those flat-screens
out there! ;)  Maybe there will be a "clunkers for green"
handouts for people like me! Fat-chance! :D
