MacBook Pro/GeForce8600M freezes using 3D textures

I use OpenGL 3D textures coupled with shader processing for color conversions and some effects in my company's real-time video mixing application.
It has been working great on thousands macs around the world for years - but it now totally fails on my MacBook Pro 2.2 / GeForce8600M, running 10.5.2:

Using OpenGL Profiler, I can clearly see my 3D textures are loaded correctly, but once a shader accesses a texture, my Mac display totally freezes, and the system log indicates:

... and so on, with no possible recovery, the only choice I have then is to reboot via ssh.

Then, I made some tests, and the only way I can use 3D textures without getting the graphics to freeze is to create a 3D texture with depth 1 (one slice) :-/

I found tens of posts on various forums complaining about the same graphics freezing problem on MBP/GeForce (while playing games, using iPhoto, etc), so I'm wondering if there's not a graphics driver problem somehow.

Did someone experience this kind of problem?
