I do have it installed, but the resolution is already detected by the
Intel driver.  If I run "915resolution -l" then 1024x600 is reported as
one of the modes

Mode 5c : 1024x600, 32 bits/pixel

But, then the xserver doesn't find mode 5c, and so the resolution is not
accepted

(II) I810(0): Not using mode "1024x600" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (800 -> 1024).
(--) I810(0): Virtual size is 800x480 (pitch 1024)
(**) I810(0): *Built-in mode "800x480"
(**) I810(0):  Built-in mode "640x480"

Also, as I said, I can set an external monitor to 1024x600.  

I think the problem is the monitor reports a maximum resolution of
800x480 and so xorg/i810 does not go above that.  

Xorg.0.log
================
(II) I810(0): VESA VBE DDC read failed
(--) I810(0): A non-CRT device is attached to pipe B.
        No refresh rate overrides will be attempted.
================

Though it seems that the monitor doesn't report any data to the xserver, so I 
am not sure where it gets the 800x480 from, or how Vista is able to go above 
the maximum resolution.
