I'm not sure if I got the same problem:
Everything worked fine until Feisty.
My card is a KM400 and since Feisty I get complete freezes (but the mouse cursor is still moveable) when i run ANY 3d related application. Even a simple glxinfo freezes the system.
I don't find any error messages in the logs and i can start the X-Server with via specified in the xorg.conf but as soon as 3D is required the fun is over.

I solved this problem for me by downgrading libgl1-mesa-glx and libgl1-mesa-dri from 6.5.2-3ubuntu7 (Feisty) to 6.5.1~20060817-0ubuntu3 (Edgy).

My card has never worked by default, even if Ubuntu recognizes it in the installation process (which it does since Edgy, I guess).
Additional options which I have always needed to get it working are:
 Option "VBEModes" "true"
 Option "DisableIRQ"
 Option "EnableAGPDMA"
