[Peter Lieven <pl@xxxxxxxxx>]

Looking further it seems that the root cause is that the CIRRUS driver
cannot be used in 12.04.3 because of this

[   579.647] (EE) cirrus: The PCI device 0xb8 at 00@00:02:0 has a kernel module claiming it.
[   579.647] (EE) cirrus: This driver cannot operate until it has been unloaded.

It seems that this is caused by the DRM driver:

[   579.639] (II) config/udev: Adding drm device (/dev/dri/card0)
[   579.642] (--) PCI:*(0:0:2:0) 1013:00b8:1af4:1100 rev 0, Mem @ 0xfc000000/33554432, 0xfebf0000/4096, BIOS @ 0x????????/65536

The DRM driver is not presend/loaded in Ubuntu 12.04.2. Subsequently the CIRRUS module loads fine
and the graphic is working as expected.

I will try if the resolution for this bug here fixes the problem:
