In a previous e-mail you mentioned this:
"if you are running a 2.6.30 kernel the testing fglrx
won't build, you have to upgrade xorg and fglrx stuff to Sid."

Does the sid xorg still apply? I would not be ready at the moment to
experiment with a sid X. Moreover, I found out that issuing
halt/reboot from a console within X would more or less shut the system
cleanly (at least no kernel panics and stuff), which would mean that
my immediate issue is solved.

Thank you for the suggestions
