Right here:
(WW) I810(0): config file hsync range 45.7143-50.5263kHz not within DDC 
hsync ranges.
(II) I810(0): Monitor0: Using hsync range of 45.71-50.53 kHz
(II) I810(0): Monitor0: Using vrefresh value of 60.00 Hz
(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): Display dimensions: (330, 210) mm
(**) I810(0): DPI set to (98, 96)
So 800x600 and 640x480 (at 60hz) got tossed out because their hsync 
value is below 45kHz. Try specifying a different hsync range in the 
config file (down to 30kHz), or you may get away without one at all if 
the monitor provides this information via ddc.
(Though personally, in my experience monitors aren't likely to provide 
anything useful or correct with EDID/DDC. I often just use 
NoDDC/IgnoreEDID and provide the information manually, but maybe it's 
more useful with TFT's...)
