Hi,
Finally had time to test those old cards, as expected absolutely all
went well.
Concerned devices:
$ lspci -nnv | grep VGA
05:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD]
nee ATI R430 [Radeon X800 XL] (PCIe) [1002:554d] (prog-if 00 [VGA
controller])
$ lspci -nnv | grep VGA
05:00.0 VGA compatible controller [0300]: NVIDIA Corporation G73
[GeForce 7600 GS] [10de:0392] (rev a1) (prog-if 00 [VGA controller])
libdrm, 2D and 3D drivers from Wheezy.
Tested using glxgear, playing 720p videos (with Xvideo and Opengl video
output), playing some basic games, google earth…
Cheers,
Vincent
