DESCRIPTION
       trident is an XFree86 driver for Trident video cards.  The driver is
       accelerated, and provides support for the following framebuffer depths:
       1, 4, 8, 15, 16, and 24. Multi-head configurations are supported.  The
       XvImage extension is supported on TGUI96xx and greater cards.

SUPPORTED HARDWARE
       The trident driver supports PCI, AGP and ISA video cards based on the
       following Trident chips:

       Blade       Blade3D, CyberBlade series i1, i7 (DSTN), i1, i1 (DSTN),
                   Ai1, Ai1 (DSTN), CyberBlade/e4, CyberBladeXP,
                   CyberBladeAi1/XP, BladeXP

       Image       3DImage975, 3DImage985, Cyber9520, Cyber9525, Cyber9397,
                   Cyber9397DVD

       ProVidia    9682, 9685, Cyber9382, Cyber9385, Cyber9388

       TGUI        9440AGi, 9660, 9680

       ISA/VLBus   8900C, 8900D, 9000, 9200CXr, Cyber9320, 9400CXi, 9440AGi
                   These cards have been ported but need further testing and
                   may not work.

CONFIGURATION DETAILS
       Please refer to XF86Config(5) for general configuration details.  This
       section only covers configuration details specific to this driver.

       The following driver Options are supported:

       Option "SWCursor" "boolean"
              Enable or disable the SW cursor.  Default: off.

       Option "NoAccel" "boolean"
              Disable or enable acceleration.  Default: acceleration is
              enabled.

       Option "PciRetry" "boolean"
              Enable or disable PCI retries.  Default: off.

       Option "CyberShadow" "boolean"
              For Cyber chipsets only, turn off shadow registers. If you only
              see a partial display - this may be the option for you. Default:
              on.

       Option "CyberStretch" "boolean"
              For Cyber chipsets only, turn on stretching. When the resolution
              is lower than the LCD's screen, this option will stretch the
              graphics mode to fill the entire LCD. Default: off.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default:
              off.

       Option "VideoKey" "integer"
              This sets the default pixel value for the YUV video overlay key.
              Default: undefined.

       Option "TVChipset" "string"
              This sets the TV chipset. Options are CH7005 or VT1621.

              Override the default Horizontal-sync value for the Xv extension.
              This is used to center the Xv image on the screen.  By default
              the values are assigned based on the video card.  Default: 0.

       Option "XvVsync" "integer"
              Override the default Vertical-sync value for the Xv extension.
              This is used to center the Xv image on the screen.  By default
              the values are assigned based on the video card.  Default: 0.

       Option "XvBskew" "integer"
              Override the default Bottom skew value for the Xv extension.
              This is used to extend the Xv image on the screen at the bottom.
              By default the values are assigned based on the video card.
              Default: 0.

       Option "XvRskew" "integer"
              Override the default Right skew value for the Xv extension.

       Option "GammaBrightness" "string"
              Set display gamma value and brightness. "string" is "gamma,
              brightness", where gamma is a floating point value greater than
