While I may agree with your diagnosis (though I'd be checking for file system damage first, hardware second), getting a "permission denied" message as the root user shouldn't shock you. root can't write to a read-only file system; root can't just traipse through kernel memory (or shouldn't be able to, but the IA32 MMU is broken in such a way that you *can't* protect memory properly and be able to use a video card for user-level programs... like, say, XF86-- aperature X drives are a lousy hack that doesn't actually protect you anyway); root can't arbitrarily read or write processor registers; root can't raise hardware interrupts (even by way of pseudo-devices). root may be the super-user, but he's still just a user in the kernel/user OS division. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
