Couple of ideas...

I notice you have an Intel video card... I have no experience with this card, but I do know that 915resolution is a BIOS hack for intel 8xx/9xx video cards to make them support other resolutions. Check the 915resolution site here.

Also... just a couple of days ago I was trying to achieve the exact same as you on my own Acer laptop, albeit with a ATI video card. The solution I eventually found (after 4 hours - I don't recall it ever taking 4 hours to change resolution under windows!! ) was to issue the command..

gtf 1440 900 60.0
where 1440 x 900 was my desired resolution, and 60.0 was my desired frequency, yours may be slightly different. For me, this outputted the following:

# 1440x900 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 106.47 MHz
  Modeline "1440x900_60.00"  106.47  1440 1520 1672 1904  900 901 904 932  -HSync +Vsync
I then added the Modeline above in the "Monitor" section of my xorg.conf and also added "1440x900_60.00" as a "Mode" in the "Display" subsection of the "Screen" section.

Relevant bits of xorg.conf pasted below for clarity...

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "HP"
        ModelName    "Desktop LCD Panel 1440 x 900"
        HorizSync    30.0 - 81.0
        VertRefresh  56.0 - 75.0
        ModeLine     "1440x900@60" 106.5 1440 1520 1672 1904 900 901 904 932 -hsync +vsync
        Option      "DPMS"

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1440x900@60" "1280x800"
Maybe one of these ideas will lead you in the right direction!
