I don't want to hijack this thread but I have some relevant data to share that others might find useful.
I have a EliteBook 9470m and have been playing around with 10.9. I have a fairly functional 10.9 instance that performs quite well.
Video both internal and external
MultiTouch Touchpad and keyboard
Docking Station with external ports
What I did to get things to function:
I was able to get internal video using the latest chimera 2.2 bootloader and using IGPEnabler=Yes IGPlatformID=01660003.
Internal NIc was enabled using the intel1000 kext commonly found within some of the various tools and forums.
While using my dock I kept the native default settings (Which I believe are IGPlatformID=01660009 and was able to get external video through both the dock VGA adapter and the Displayport on the dock. Undocking and redocking caused issues with the video and required a reboot to resolve.
As far as audio I was able to use the VoodooHDA 2.8.4 and get output on the internal speakers. I have not tested the headphone jack or internal microphone.
Full multitouch on the touchpad was enabled using the VoodooPs2 kext I found on Google Code. I had previously been using a modified ApplePs2 kext to get basic keyboard/mouse functionality.
For USB I had to use the generic USB kext which let me mount/dismount external usb drives and USB keyboard/mouse. The USB from the docking station worked natively, but once a device was unplugged then replugged it was no longer functioning until the generic USB kext was in place.
Still under exploration is the internal WiFI. I actually have a HP Broadcom BCM4312 (deviceID=4315)but none of the BCM kext I have used have been able to enable it. However, it does show up when using a sysinfo app I found when browsing the forums.
Internal bluetooth is also not enabled nor is it actually listed when using the sysinfo app. It is an intel version. Any input on that would be helpful. (edit) I later put in the Intel WiFi card and removed the Broadcom WiFi card since I was unable to get it to function. Upon reboot, the Bluetooth was enabled and working fine without any modification. Clearly the Bluetooth and WiFi cards are connected and enabled together somehow.
