I assume 269 and 295 are related to 377 and 380. I remember i had a lot of
pain getting a Geforce 440MX to do 16:9, but it was all in the modelines.
There are some modeline calculators on the web, but be warned that some of
them produce bad output. I did eventually get it to work after a lot of
trial and error.

Also because of this;

(II) MACH64(0): <default monitor>: Using hsync range of 30.00-85.00 kHz
(II) MACH64(0): <default monitor>: Using vrefresh range of 55.00-75.00 Hz
(II) MACH64(0): <default monitor>: Using maximum pixel clock of 160.00 MHz

you may need to set the ranges in your xorg.conf instead. check the
monitors specs first tho.
