Okay, last post for this moment. I can confirm that sudo apt-get remove --purge nvidia-common nvidia-current nvidia-settings solves the problem.
Btw. I had also checked for /etc/X11/xorg.conf and there were none. Why? Because I consider it buggy when lspci finds no nvidia and no xorg.conf prescribes one, that Xorg actually tries loading some ... . If you compare the proper loading (as of now) with the 'all wrong' one in the OP (above) line by line: [ 19.169] (--) Depth 24 pixmap format is 32 bpp [ 19.169] (II) RADEON(0): [DRI2] Setup complete [ 19.169] (II) RADEON(0): [DRI2] DRI driver: r600 [ 19.169] (II) RADEON(0): [DRI2] VDPAU driver: r600 [ 19.169] (II) RADEON(0): Front buffer size: 9000K [ 19.169] (II) RADEON(0): VRAM usage limit set to 219499K [ 19.169] (==) RADEON(0): Backing store disabled [ 19.169] (II) RADEON(0): Direct rendering enabled [ 19.169] (II) RADEON(0): Setting EXA maxPitchBytes [ 19.169] (II) EXA(0): Driver allocated offscreen pixmaps [ 19.169] (II) EXA(0): Driver registered support for the following operations: [ 19.169] (II) Solid [ 19.169] (II) Copy [ 19.169] (II) Composite (RENDER acceleration) [ 19.169] (II) UploadToScreen [ 19.169] (II) DownloadFromScreen [ 19.169] (II) RADEON(0): Acceleration enabled [ 19.169] (==) RADEON(0): DPMS enabled [ 19.169] (==) RADEON(0): Silken mouse enabled [ 19.169] (II) RADEON(0): Set up textured video [ 19.169] (II) RADEON(0): [XvMC] Associated with Radeon Textured Video.

However, when the nvidia-driver is gone, it miraculously finds GLX on the ATI card? Thanks anyway very much for helping me to get composite back, Dave!
