I don't have one, and I don't have a config file, but it
should be
pretty easy based on looking at the hardware at
www.everymac.com.

800x600
ATI rage

Use some pretty conservative sync and refresh rates to start
with, and
it should work.

That WON'T work.
This kind of iMacs has weird monitors which need a fixed
60kHz 
horizontal frequency. The 800x600 timing is non-standard (
89Hz or so ) 
while X will pick something more standard which the monitor
will refuse 
to display.
1024x768 at 75Hz will work since it is both standard and
uses 60kHz.
Using conservative timings will pretty much ensure that the
monitor 
won't display anything.

have fun
