And the xorg.0.log message is saying that the psb_dri.so is expecting psb.ko to be 5.x.x-7.0.0, but it see a psb.ko with version of 8.0.0 was loaded. It means that the psb_dri.so is a little bit old.

In the kernel driver tree, umg-moorestown-drm-tg, psb_drv.h, it define the version info for kernel driver psb.ko:
#define PSB_DRM_DRIVER_DATE “20081216”
#define PSB_DRM_DRIVER_MAJOR 8
#define PSB_DRM_DRIVER_MINOR 0
#define PAB_DRM_DRIVER_PATCHLEVEL 0
During driver load, this version info will be loaded and checked against the user mode 3D driver psb_dri.so, psb_dri.so should be in sync with psb.ko, and both driver is updated from time to time, the versioning will updated if they need to be resync up.
Hope this answer your question?

Concerning my earlier email concern DRM versioning, how does the version in the following Xorg.0.log text relate to the DRM version in the kernel and libdrm:
and I can work with versions 5.0.x - 7.x.x
Please update either this 2D driver or your kernel DRM.
