nouveau kernel module causes null pointer reference in X start

[Pauli]

Binary package hint: nouveau-kernel-source

Nouveau kernel module crashes when Xorg is starting in bo allocation. This makes whole system unusable because going back to terminal after this is not possible.

Problem ha been reproducing with high propability after upgrade to Karmic but not everytime. So it looks like some race condition that triggers often in this system.
