Unfortunatelly, still no luck.

I've added:

HorizSync       28-100
VertRefresh     60-100
ModeLine        "1280x800" 83.46 1280 1344 1480 1680 800 801 804 828
ModeLine        "1280x1024" 108.0 1280 1328 1440 1688 1024 1025 1028 1066


To "Monitor" section, but my Xorg.0.log still gives me:

(II) I810(0): Laptop LCD: Using hsync range of 28.00-100.00 kHz
(II) I810(0): Laptop LCD: Using vrefresh range of 60.00-100.00 Hz
(II) I810(0): Not using mode "1280x1024" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (1280 -> 2048).
(--) I810(0): Virtual size is 1280x800 (pitch 2048)
(**) I810(0): *Built-in mode "1280x800"
(**) I810(0): *Built-in mode "1024x768"
(**) I810(0):  Built-in mode "800x600"
(**) I810(0):  Built-in mode "640x480"
(++) I810(0): DPI set to (100, 100)

Maybe this got something to do with not-existant modes:

As you can see, none of listed modes has resolution of 1280x1024? Why, if 
915resolution correctly reports all supported resolutions:
