This is a basic X setup problem.  Your /etc/XF86Config contains
incorrect information about the monitor.  Check the following
information, taken from a functional CPi 266:

Section "Monitor"
   Identifier      "Primary Monitor"
   VendorName      "Unknown"
   ModelName       "Unknown"
   HorizSync       31.5-57.0
   VertRefresh     50-90
   Modeline  "1024x768"   75.00 1024 1048 1184 1328 768 771 777 806 -hsync -vsync
EndSection

Section "Device"
   Identifier      "Primary Card"
   VendorName      "Unknown"
   BoardName       "NeoMagic (laptop/notebook)"
#    Chipset    "NM2160"
#    IOBase     0xfea00000
#    MemBase    0xfd000000
#    VideoRam   2048
#    DacSpeed   90
#    Option     "linear"
#    Option     "nolinear"
#    Option     "sw_cursor"
#    Option     "hw_cursor"
#    Option     "no_accel"
#    Option     "intern_disp"
#    Option     "extern_disp"
#    Option     "mmio"
#    Option     "no_mmio"
#    Option     "lcd_center"
#    Option     "no_stretch"
EndSection

Check particularly that these lines are correct for your monitor:

   HorizSync       31.5-57.0
   VertRefresh     50-90
