I finally came out with a perl script that parses XFree86 log file and
at least on my machine, it gives accurate results.

open (IN,"/var/log/XFree86.0.log");

foreach (<IN>) {
        next unless ( /Virtual size is (\d+x\d+)/ || /Modeline/);
        next unless /Modeline .$1/;
        ($pixelclock,$hdisplay,$vdisplay,$htotal)=(split /\s+/)[4,5,9,8];
        $pixelclock =~ s/\.\d+//;
        last;
}
close (IN);


Any comment welcome.
