Sorry folks.  Dumb mistake on my part.  I needed to re-run the proprietar
y
ATI driver installer to get fglrx modules for the new kernel.

In the meantime, I found that the free r500 driver, which the SL live dvd

uses for my machine, is nearly good enough for my purposes.  The only
problem is that I can't get it to give me a pseudocolor visual.  With the

proprietary driver, I put a line
Option	    "PseudoColorVisuals" "on"
in the device section of xorg.conf, but that doesn't seem to work for r50
0.
 Does anyone know whether it's possible to get a pseudocolor visual with 
the
free driver?
