I had similar problem with i815 video chipset. It turned out that the
DAC speed hardcoded in the XFree86 driver was too small (presumably
corresponding to the worst available in the i8xx line). According to
Intel website, i815 has a 230 MHz 24 bit DAC, so add the following line
to the "Device" section of your XF86Config:
DacSpeed 230
Hope that'll help (it did for me :)
Roman.
