Given the responses that I received about the xorg.conf keywords being 
case insensitive, I am uncertain what I did to get rid of the error.  
Now that I have booted into Linux, when I look at my new xorg.conf, 
there is no modeline at all any more.  I do not know if the differences 
between the i915 and the i945 are causing your problems or what is 
happening.  I looked through my Xorg.0.log file, and it looks very 
similar to yours.  I do not have the lines about hsync range not being 
correct, but I'm not certain hsync matters for LFPs.  I also do not see 
the same type of errors I had when my i810 driver wasn't detecting my 
resolution properly in your xorg.log.  The only major difference I see 
in your log files is that my modes 60-62 have information in them for 
the 1366x768 mode.  I do not know why the information for your 1280x800 
isn't in one of those modes also.  That may be the issue, but I don't 
know how to resolve it.

Sorry that I can't be of more help,
