got a new monitor, trying to reconfig xorg

[Jonathan Horne]

i just brought home new samsung 22" widescreen LCD.  so far, i cannot get xorg 
to take anything other than standard CRT type resolutions, such as 1280x1024.  
i took at look at my Xorg.0.log, and saw this:

(II) I810(0): 720x400 at 70Hz
(II) I810(0): 640x480 at 60Hz
(II) I810(0): 640x480 at 67Hz

(II) I810(0): Will use BIOS call 0x5f05 to set refresh rates for CRTs.
(--) I810(0): Maximum space available for video modes: 12288 kByte

(II) I810(0):   HorizSync 30-81
(II) I810(0):   VertRefresh 56-75
(WW) I810(0): config file vrefresh range 50-100Hz not within DDC vrefresh 
range 56-75Hz

the first part, seems to be the normal video modes that i would expect to see 
from an i810 graphics card, but then right below that, i see video modes that 
would be preferred on my new monitor (1680x1050) in a section 
called "Supported Future Video Modes".  does this mean there is a chance i 
might see proper resolutions for my new monitor, without upgrading to some 
other video card?

my computer has a 915G:

(II) I810(0): Integrated Graphics Chipset: Intel(R) 915G
(--) I810(0): Chipset: "915G"

if anyone who has a similar setup (with a wide screen monitor), i would 
appreciate if i could be pointed in the right direction.

cheers,
