Hi all,
To get the tv-out working you can use the vesa driver instead of radeon 
driver. You'll have no acceleration, but works well with most standard 
resolutions and color depths.
I use it to see movies on tv. To avoid changing the config file back and forth 
and restarting X what I do is start another X session on a different virtual 
terminal using a different config file (X --xf86config XF86Config.vesa)
Using the ATI propietary driver may do the trick too, but this is a bad path 
to follow (to get overlays on TV you must start X without monitor so TV is 
primary, only 24 bits, only x86, lockups....)

Gene, DRI on 9200se works nicely (I get 1400 fps with glxgears on 16 bit 
color), but you may have issues with the xorg DRM module. Simply use the 
radeon module from the linux kernel and it will work.

By the way, as of xorg 6.8.0/1 there seems to be a regression on the radeon 
driver that breaks the vesa driver (I still couldn't test 6.8.2rc). After 
exiting the first X session using radeon, you'll be not able to start X using 
vesa anymore until the machine is rebooted. This didn't happened with xorg 
6.7.0.
I filed a bug in bugzilla under Driver/Radeon (bug 1345) long ago, but nobody 
seems to have noticed. Hope it has been fixed (could somebody check if it is 
still there on 6.8.2?)

Sorry if this breaks mail threads, I'm replying to the xorg Digest...

Best regards, and happy new year,
Miguel Angel
