rv100, second video card, tv out

[Eric Moreau]

Hi everyone,

Here is a pretty useless post because it involves old hardware,
but i'd like to know if anyones has a clue on this:

Software (uname -a on Fedora 14):
Linux (hostname obfuscated) 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Hardware (snippets from lshw):
 description: Motherboard
       product: P5GC-MX
       vendor: ASUSTeK Computer INC.
 description: CPU
          product: Intel(R) Core(TM)2 Duo CPU     E4500  @ 2.20GHz
  description: Display controller
             product: 82945G/GZ Integrated Graphics Controller
             vendor: Intel Corporation
 description: VGA compatible controller
                product: Radeon RV100 QY [Radeon 7000/VE]
                vendor: ATI Technologies Inc

I would like to use the old radeon card for tv-output.
If i use it as the primary video card, everything goes well, tv-out
is detected and usable with xrandr.

If I use the onboard intel video as primary video, i get this from dmesg
