5) Configuration

   The driver auto-detects all device info included memory size, so
   use the following device section in your XF86Config file:

	Section "Device"
		Identifier	"NeoMagic"
	EndSection

   or let xf86config or XF86Setup do this for you.

   But if you have problems with auto-detection, you can specify:

      VideoRam  - in kilobytes
      DacSpeed  - in MHz
      MemBase   - physical address of the linear framebuffer
      IOBase    - physical address of the memory mapped IO registers


6) Driver Options

    "no_linear"     - banked framebuffer mode
    "no_accel"      - software rendering only
    "sw_cursor"     - software cursor only
    "no_mmio"       - use I/O space directly
    "intern_disp"   - enable internal display (default)
    "extern_disp"   - enable external display
    "no_stretch"    - disable stretching of lower resolution modes on panel
    "lcd_center"    - center lower resolution modes on panel

     NOTE: Stretching of panel image is on by default for lower panel
     resolutions.

   Options useful for special lcd mode setting (should not be needed):
    "prog_lcd_mode_regs"       - set special lcd mode registers (2070 default)
    "no_prog_lcd_mode_regs"    - don't set lcd mode registers (non-2070 default)
    "prog_lcd_mode_stretch"    - force lcd mode regs if stretching is enabled
    "no_prog_lcd_mode_stretch" - no lcd mode regs if stretching (default)

   Option for subnotebooks and other laptops with uncommon size panels:
    "override_validate_mode" - disable LCD mode checking

     WARNING: Disabling mode checking will allow for invalid modes that
     could damage your LCD.

7) Known Limitations

   * External monitor support on the NM2070.
   * Banked, or no_linear mode on the NM2070.
   * Horizontal centering for lower than panel resolution on NM2070.
