Weird display problem

[Francis X. Maier]

I had to wipe my drive and reinstall YDL 3.0 this week, and now, no 
matter what I do, I can't get a GUI to come up.

I'm running a 350 mghz iMac with a built-in (i.e., soldered-on) ATI 
Rage RL/VR card (8 M video ram).  YDL keeps telling me it only has 512 
k video ram, but I've been to the local Apple Store for a complete 
diagnostic to check out all my components.  Everything is working 
normally.  So YDL is reading my card wrong.

I've gone into /etc/X11/XF86Config and

-- uncommented "Load DRI" in the "Modules" section
-- added "Load r128" in the "Modules" section
-- uncommented "BusID" in the "Device" section and added the location 
0:16:0 of my card.

I've been gettinng either of these two messages:

"Parse error on Line 110 of Section:Device in file /etc/X11/XF86Config. 
  The BusID requires a quoted string to follow it.  (EE) Problem parsing 
Config file.  (EE) Error from xf86HandleConfigFile.  Fatal server 
error: no screen found."

or

r128(0): Cannot read V_BIOS (5)  Fatal server error: Caught signal 11: 
server aborting."

Any idea what I'm doing wrong?
