I have a Sony laptop with an i915 card, and I have not needed 
915resolution since Breezy.  You may want to uninstall 915 resolution, 
and get this working directly with the xorg.conf.

I have attached my current xorg.conf for reference.  I do remember that 
I had to mess with it a bit in Dapper to get everything working 
properly, and so I can probably help a bit to try to figure out what is 
going on with yours, too.  As you can see from my xorg.conf, my laptop 
screen is 1366x768.

The first place that I started looking is in /var/log/Xorg.0.log.  It 
had informational messages in there that told me why it wasn't selecting 
the resolution I wanted.  It may have to do with sync ranges configured 
for the monitor, or other issues, but we should be able to figure this 
out.  Let me know if you would like to pursue this further.
