Replying to myself..but I thought I'd add some details.

To use a Savage card with TV out, you *must NOT* have the X driver 
option "UseBIOS" "off" set. It will not work. The default for UseBIOS 
is on, and you must keep it that way.

Then, you can use the "s3switch" program (downloadable from above 
website) to switch between TV, LCD, and CRT outputs. This uses the 
video BIOS to do the switching, so it really ought to work for all 
boards.

If you're having problems, it's probably a good idea to download the 
latest version (1.1.27t currently) of the driver from the website. This 
is newer than the version included in XFree86 4.2.1.

Until the next version is released, you may have to apply the following 
patch to make s3switch work if you're using a Shuttle SK41G (this patch 
came from the author, so I assume it'll be included in a new version at 
some point):
