Knoppix 6.2 runs where Knoppix 6.7 does not!

Thanks for pointing me to this. Actually, I think it may be a problem
with the newer xorg server version, maybe in combination with the radeon
firmware inside the "linux-firmware-nonfree" package.

For your recommendation: It may be safer to run radeon-hd cards with
cheatcode "knoppix nocomposite", "knoppix nomodeset" or even "knoppix
nodrm" in Knoppix 6.7. The first one just disables the composite
extension used for 3D, while the second and third one disables some or
all acceleration (possibly falling back to vesa).

The reason why 6.2 may have worked better was that there was no kernel
mode setting requirement in the older xorg version, but now with
xorg-core 1.10, many radeon-hd cards just won't work without kms being
enabled, and Knoppix falls back to vesa, if the card is still responding
and isn't blocked for some reason.
