Yes, the damn proprietary drivers. I should have thought of them,
should have thought of "modprobe radeon" (which I tried so often on
my PPC with Ati graphics, some years ago)...
Anyway: a big thank you for directing me to the source of the problem,
P.S.: I'm too tired now to figure out how to close this bug, please do
it for me as well (or I can investigate more on Saturday).
