I'm not real sure how xrandr works, but if I run xrandr at a prompt I
get this:
 SZ:    Pixels          Physical       Refresh
*0   1280 x 800    ( 433mm x 271mm )  *60
 1   1024 x 768    ( 433mm x 271mm )   60
 2    800 x 600    ( 433mm x 271mm )   60
 3    640 x 480    ( 433mm x 271mm )   60
 4    640 x 350    ( 433mm x 271mm )   60
 5    640 x 400    ( 433mm x 271mm )   60
 6    720 x 400    ( 433mm x 271mm )   60

 10  1280 x 720    ( 433mm x 271mm )   60
 11  1280 x 768    ( 433mm x 271mm )   60
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

Where is it even coming up with these resolutions since I only have 2
specified in my conf file? You'll also notice that the resolution I
want, 1280x1024, is not even listed. 

>From a hardware standpoint, the internal controller, or the one that
drives the internal display probably does not support 1280x1024, but the
external controller does. 

For example, if I boot into Windows XP I have different resolution
options depending on which display I'm trying to use. 

Can you give me more specific details on how you're using xrandr?

Thanks,
James
