No need for all that.. All you need is one xorg.conf for the graphics 
card, and one for the tv out.

I saved my xorg.conf as xorg.conf.monitor, just before i started on the 
350 section of jarods guide. Once i had a working 350 setup I saved that 
as xorg.conf.TV.

Depending on which I want to boot in, I have xorg.conf linked to one of them

So all you need to do is backup your current conf as something else, and 
then modify it to use your graphics card instead. Then you can switch 
back and forth easily

Hope you can see what i mean, if someone wants to explain it better be 
my guest..
