Video out with Radeon 9100LE (Rebadged 8500LE)

[Chris Holmes]

Hi
I've been trying to get video out to work with the Radeon 9100LE,  
either S-Video or composite, to use my old computer as a media centre.

Distribution: Ubuntu Hardy 8.04
Xorg 7.1 - ATI driver 6.6.8

Xrandr doesn't seem to find the s-video/TV output - output as follows:

Screen 0: minimum 320 x 200, current 1280 x 768, maximum 1920 x 1200
VGA-0 disconnected 1280x768+0+0 (normal left inverted right x axis y  
axis) 0mm x 0mm
DVI-0 disconnected (normal left inverted right x axis y axis)
   1280x768 (0x6d)   80.1MHz
         h: width  1280 start 1344 end 1480 total 1680 skew    0  
clock   47.7KHz
         v: height  768 start  769 end  772 total  795            
clock   60.0Hz

(yes i have nothing connected - i'm accessing the box remotely via VNC  
right now)

I've tried the following options in xfree86
         Option "TVDACLoadDetect" "TRUE"
	Option "TVStandard" "PAL-B"
	Option "ForceTVOut"	"TRUE"
	Option "DefaultConnectorTable" "TRUE"

The best i've got is with the "DefaultConnectorTable" option, which  
gave me a white, blank screen and the following xrandr output.

My next point in call was to try the 6.6.9 drivers. That had the same  
results.

I then tried the 6.6.3 drivers patched with GATOS - with the following  
options this cloned the display at 800x600 resolution with
"Option "TVOutput"	"PAL"
  However, running XMBC crashed the whole computer, and X would crash  
taking down the whole system after the computer was running for 6-15min

    400x300        85.0     75.0     72.0     60.0


Attached is the Xorg log files and xorg.conf. Note that no displays  
where connected, hence the strange behavior - but you can see where  
one is loading rage_theatre and the other isn't.

Physically the card appears to have a separate rage theatre chip on  
it, rather than the internal rage theatre found on later cards.

It appears that the newer driver doesn't load rage theatre module - is  
there any way to force loading of the theatre driver? The other option  
I thought is a buggy bios on the card, as the documentation suggests  
that xorg-ati reads the output table the card. However the  
'DefaultConnectorTable' option doesn't seem to help.

Any ideas/patches/hacks would be appriciated.

Regards,
Chris Holmes
