If you're using Knoppmyth, /etc/init.d/install-nvidia-debian 
(/etc/rc5.d/S90install-nvidia-debian) is supposed to autodetect and 
regenerate the X config at boot time.  It doesn't always work, however 
:-) and you might invoke mkxf86config instead.  Although, since you're 
talking about xorg.conf you probably aren't using Knoppmyth...

I would DEFINITELY install the nvidia binary drivers, and not use the 
built-in "nv" driver; the TV support (and a bunch of other things 
besides) work noticeably better.  Also, the nvidia binary driver 
supports Xvmc fully, and there is a special output mode for MythTV that 
uses the nvidia driver's extended Xvmc support to achieve significantly 
lower cpu usage.

As an added bonus, the nvidia binary drivers will either generate a 
correct xorg.conf file for you, or at the very least provide decent 
documentation on how to fix said file yourself.
