Lost QE/CI with GMA950 after 10.5.6 Update

Lost QE/CI with GMA950 after 10.5.6 Update.

iWork ceased to work correctly, and trying to open the Graphics section of System Profiler results in a kernel panic.

 

The issue seems to be caused by

 

sh-3.2# kextload /System/Library/Extensions/AppleIntelGMA950.kext 
kld(): Undefined symbols:
_gIOFBZero32Data
kextload: kld_load_from_memory() failed for module /System/Library/Extensions/IONDRVSupport.kext/IONDRVSupport
kextload: a link/load error occured for kernel extension /System/Library/Extensions/AppleIntelGMA950.kext
link/load failed for extension /System/Library/Extensions/AppleIntelGMA950.kext
(run kextload with -t for diagnostic output)

Is it just me or does anyone get the same?

 

Before the Update it worked fine...

 

Replacing /System/Library/Extensions/IONDRVSupport.kext with a pre-10.5.6 works, but I'd consider it an ugly hack. Any better ideas?
