That's pretty much it... there is a fair amount of code in there (in 
sis_bridge.c) to detect what is connected (VGA, LCD, TV) and to set up the 
hardware overlay(s) appropriately.  The only thing that needs "user 
intervention" is when there are 2 devices connected and the chipset only 
has 1 overlay, for which case I added the "VIDIX_CRT=N" env variable.
Of course I haven't tested support for multiple overlays, etc (some 
chipsets like 315/M650/651 have 2 overlays) so a lot of this could use 
work.

I also added a VIDIX_CKEY=0xRRGGBB variable, but it was removed before 
committing.  The intent was to allow colorkeying for fbdev:vidix (or 
cvidix I guess) so that framebuffer-based apps that exec mplayer can 
provide a gui overlay...  I suppose a better way to do this would be to 
add a commandline/driver option to set it?
