Bronya's latest 10.9.2 RC5/RC6/RC6_fix kernels do allow to update/install 10.9.2 and 10.9.3, but I'm experiencing trouble with graphics acceleration with my nVidia cards (GeForce 9800GT and/or GeForce GT610). That's an issue I was not experiencing with previous Mavericks versions or previous OS X releases, so it's work in progress...

Thank you!

Following axmanA's research, graphics issues encountered since 10.9.2 are now sorted. The Precision 670 with GeForce 9800GT can now run 10.9.2/10.9.3/10.9.4 with Bronya's 10.9.2 RC5/RC6/RC6 fix/RC7 kernel with full (non-lagging) QE/CI if kexts IOPCIFamily + AppleACPIPlatform are replaced by versions from 10.9.1 or IOPCIFamily patched version from axmanA is used (I sticked to 1st option).
 
All running well, but there are small graphics defects like picture corruption when doing screen dumps, but that has been reported by other AMD kernel users too, so it's not specific to the Dell Precision 670 system. Other than that, everything looks perfect so far.  :thumbsup_anim:

Reverting to those 10.9.1 kexts also restores the ability to boot Mavericks on the Precision 670 off a USB external HDD. This was also lost from 10.9.2...

Was running RC7, but experienced out the odd sudden system freeze when starting Skype. Reverted to RC6_fix (for old CPUs) and the freeze does not happen, so sticking to that. Need to recheck Sleep & Wake though...

RC5 gives me occasional small graphics artefacts, so I dismissed that one.

RC6 and RC6_fix run Ok, but I cannot get screen to wake after sleep. Screen stays off for some reason. I also have to boot without cache or Skype will freeze system when launched.

RC7 runs Ok and properly wakes system from sleep. However, and as indicated above, I have to boot without cache or Skype will also freeze system when launched.

 

The Skype freeze happens even if I manually rebuild cache after booting without. Something for Bronya to work on maybe.

Issues with Skype freezing the machine now sorted. It was just due to kernel cache not generating properly through myHack. All Ok after manual cache rebuild.

Up to 10.9.5 now. This new update proved a bit problematic at the onset (it would not boot to OS X desktop) and subsequently required rolling back IOHIDFamily kext from 10.9.4 (v2.0.0 - 503.200.2) to complete startup. A better alternative is to rollback IOHIDFamily + Sandbox + System kexts from 10.9.1 as that also avoids all kernel symbols related error messages during startup and subsequent system problems.

 

Naturally, I kept the rollback to 10.9.1's AppleACPIPlatform + IOPCIFamily kexts to retain 9800GT graphics support.

 

Still using same AMD kernels from Bronya, namely 10.9.2 RC7 (old) or 10.9.4 RC1/RC2.

NB: No change whatsoever to Chameleon (version, boot plist) or SMBIOS profile, but SysProfiler no longer reports 2 x dual-core Intel Xeon each with 2 cores. Instead, it reports a single dual-core Xeon with 4 cores. Not that it changes anything, but... Info stays the same with different versions of Chameleon, therefore it does not seem bootloader related.
