Here's a new version - removed the #define, also fixed a mistake in setup
for non-svideo.

This driver provides some access to the Brooktree bt869 found on some video
cards (like the 'Voodoo3 3000'). Typically, the output can be either an
s-video connection or composite video. Resolutions supported using the
-chip's built in configurations are 640x480 or 800x600. Other possible
-implementations may allow for double resolutions with some decimations
-(e.g., a monitor running at 1280x960 but the TV out getting every other
-pixel for 640x480).

-Stanards: (US) NTSC or PAL (PAL untested)

+Standards: (US) NTSC or PAL
+Resolutions: 640x480, 800x600 and 720x576 (PAL only)
Depths: 16 bit or 32 (I forgot if 24 bit worked OK, it probably does)
Colorbars: Switch on the built-in color bar generator. (FYI- using a blue
filter, you should see only alternating bright stripes of equal brightness.
Adjust your TV's color and saturation if this isn't the case.)
+SVideo: composite or s-video output. Also, theoretically, RGB output, though
+this isn't tested and will require that your card presents all three DAC outputs
+(the 3dfx Voodoo3 doesn't)
In your XF86Config file, you should have these entries for NTSC output:
ModeLine "640x480NTSC" 28.195793 640 656 658 784 480 520 525 600
