Read the debugging output more carefully.  Capture it to a file by doing
(from csh):

/usr/X11R6/bin/X -probeonly >& /tmp/out

Then examine /tmp/out.  You will almost certainly see a line in there
along the lines of:  
mode "1024x768i" requires a HSync of 48.85 Hz.  Deleted.

So by the time your config is completely read, there really -is- no
valid mode 1024x768i defined.

The fix is to be a little more generous in defining what sync rates your
monitor can handle.  You should, however, carefully consider if doing
this will damage your monitor.
