I'm running the latest versions of these drivers, since the stock radeon
driver (radeon_drv.so) doesn't start on my machine (x86-64 running FC5),
and hasn't started since the release based on:
        xorg-x11-6.8.2-37.FC4.48.1.x86_64.rpm .
The symptom is a dark screen, and (I believe) a complete system lock up.

The drivers work OK.  glxgears performance is about 1820 frames/sec.

A few questions:

How can I enable X-Video?  The documentation seems to indicate that
X-Video and OpenGL are mutually exclusive.  (I've already posted this
question in another thread.)

What does ati-fglrx-config-display do?  No documentation anywhere.  A
quick glance at the code makes me think that it switches between the
fglrx driver and some other driver, probably the xorg standard radeon.
Since the radeon driver doesn't work at all, I don't want this.
