Kernel Ooops with i945

[Tino Keitel]

Hi,

yesterday I tried again to get something usable out of the Intel 2.6.x
driver on my Mac mini Core Duo with i945.  So I installed the latest
git versions of the kernel, drm and mesa, Intel driver 2.6.3 with UXA
enabled and a pre-1.6 version of the Xserver, and got a kernel ooops:
