I've a problem with the ATI drivers of a new ALU imac (the lowend 20" with 2400 card) with Tiger:

This is my crashing code:

Thread 0 Crashed:

I've thought the problem was in VBOs but disabling them doesn't change anything (except the call at backtrace level 7), so I tried to run the OpenGL profiler but it reports the following thing:

This version of OpenGL Profiler is known to have incompatibilities with your updated OpenGL framework.

You may continue to use this application but some functionality may not work properly. Would you like to quit now or continue using OpenGL Profiler?

Then it crashes as soon as I "launch" the app, if I try to "attach" the profiler to the app it crashes too. There is a version of the OpenGL profiler compatible with ATIRadeonX2000GLDriver?

Plz note that I've to fix the game for THIS configuration, so upgrading to Leopard it's not an option (I've a Leopard drop-in upgrade DVD sitting on the desk waiting for this bug fix :) )
