You did not say...but if it is a separate card, it should be active on 
both outputs, unless, exactly like the BIOS thing, it needs to be turned 
on or initialized. and it sounds like THAT is happening in X.

I presume you have an output line in xorg.conf which sets output to 
something like 'CRT,TV'....how you get the 'TY' bit prior to then I do 
not know.
