Help with resolution

so heres the scoop, I have a inspirion 8500, the native resolution is 1280x800, now, i have edited my /etc/X11/xorg.conf file and added the resolution. But it doesnt show up in my system settings/desktop in gnome or kde. the highest resolution I can get is 1024x768, after that the display says it is changed, but the screen hasnt changed, ive been scratching my head for a while on this one, any ideas? Please help, you guys are great.

# Multiple FontPath entries are allowed (they are concatenated together)

# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:

# For example, a german layout can be obtained with:

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
# If you'd like to switch the positions of your capslock and

I've had a similar problem, and would love an answer... My xorg.conf file has plenty of resolution modes
    Subsection "Display"
        Depth       24
        Modes "1280x1024" "1152x864"  "1600x1200" "1024x768" "800x600" "640x480"
but the KDE resizer thing only shows up to 1024x768. Any tips would be greatly appreciated... linux is nearly unusable at this resolution for my purposes.

Have you researched your monitor's manufacturer's website to see if these are the proper horizontal and vertical ranges for your monitor?
