[Intel-gfx] Intel/Pineview graphics won't load 1024x600 resolution in X11

[Gabriel M. Beddingfield]

Hello,

First: if this is the wrong place to ask, would you please 
point me to the appropriate channel.

I'm using an N450 processor with the GMA 3150 Pineview graphics
system.  When X11 starts, it seems to detect that it's capable of
1024x600, but then loads 800x600 instead.

     (II) VESA(0): Modeline "1024x600"x0.0   45.00  1024 1077 1112 1200  600 604 609 625 -hsync -vsync (37.5 kHz)

Any idea why it won't load the correct resolution?

Basic info:

     OS:            Ubuntu/Jaunty with several backports
     X.Org Xserver: 1.6.0
     kernel:        2.6.33.2-rt13
     intel driver:  2.11.0
     libdrm:        2.4.18

Possibly related:

     /etc/modprobe.d/i915-kms.conf has this:

         options i915 modeset=0

     When it has modeset=1, the console has a nice 128x37
     display, but X11 won't load.

Thanks in advance,
Gabriel
