I can only comment a bit on the G400 card...

Apart from me having the official S-Vid/Composite (using the composite
output, I don't get to use the TV that has RGB in) this is similar to me --
I have it connected to the second head, can see the BIOS but not Linux
booting. I believe this is due to the initialisation of the kernel which
switches off the TV support until you reactivate it -- I have it set up with
a custom modeline and it gets activated at the end of the boot sequence.
You could probably patch the kernel to do this/not do this earlier on, but
I've never bothered.

If you're running on a standard TV (not high-definition) I wouldn't bother
resolution-switching.

You should be able to use the RGB TV modes in X11 -- at worst if you have
the console working you should be able to have a line
Option "UseFBDev" "on"
In your xf86.conf/xorg.conf file.
You can download a binary driver from Matrox which is still being maintained
