You might want to take a peek at:
http://sdb.suse.de/en/sdb/html/olh_ppc_apple_tft.html

They recommend using:

video=aty128fb:vmode:22

I used an ATI rage 128 for a while with my cinema display.  I had
occasional problems when I rebooted.  It worked fine in OSX, but it did
not always initialize properly (i.e. sometimes it would not display the
"happy mac" or open firmware, but would work always with OSX).

I use a Radeon now, which works flawlessly.

If you can't see a tty, then you can't use X (from what I have seen).
So the first problem is make sure you can see the tty.  It may work
using the video line suggested in the SUSE page above. 

Let me know if this helps.

I have the modelines in my XF86Config-4 file.  The one I use is:

# apple cinema display
Modeline "1600x1024"   108.0   1600 1616 1656 1704 1024 1027 1030 1056
-Hsync -Vsync -Csync
