ATI proprietary drivers installation issue on debian testing

[dagecko@free.fr]

Hi,

I updated my debian stable into testing... My bad, since I have
an ATI graphics card...
I now can't install their drivers, even if I fall-back with the
previous driver version and/or previous kernel-version (stable).

Anyway. Here is the purpose of this mail. It seems newer ATI
proprietary drivers expect Big Kernel Lock to be activated in the
kernel, which is not the case.

Ati installation log will be given below.

My question is, how far could I expect Big Kernel Lock to be
providen in future updates of the kernels ?

For now, I think I'll do the old-job, recompiling the kernel,
since I can't find a solution (and don't want to go back to
debian stable)...

Thanks in advance
