The driver does not seem to detect this 1366x768 resolution at all, I
guess your screen does not report it correctly.

The Modes line isn't really used anymore.
You might want to try forcing a mode with the following:
* run something like 'gtf 1366 768 75' to get a ModeLine for 1366x768 at
75hz (or whatever refresh rate you want)
* add this ModeLine to your xorg.conf in the Monitor section
* add a PreferredMode line to your Monitor section
Option "PreferredMode" "1024x768_78.00"
(or something like
