I got a solution for you I figured out today for my probook 4720s core i5 2,67 Ghz. Finally it's working. Think it's almost the exact hardware (incl. Chipset, PCIe and so on)

So this is how I did it:

-Boot from iatkos S3 V2 with flags -v busratio=18 (think it's the same for you)
-Select:
--anval loader
--whole USB section (to fix the problems)
--apple PS2 - DO NOT SELECT ALSO THE VOODOO AS THIS DOES NOT WORK!
--SELECT the modified kernel qoopz 10.6.3 - this makes it
--Select USB fix
--Select your hardware kext drivers

Wait for the install to complete. Restart. boot with the same flags as above

And...voilla...it's working including the keyboard and the trackpad

Now adjust the graphics - the system knows it's accelerated graphics but you have to change the res to 1600x900 in my case so:

Go to terminal and navigate to:

/Library/Prefrences/SystemConfiguration/

All you have to do is edit the com.apple.Boot.plist and add two lines there

type:

sudo su
your password
cd /
cd /Library/Preferences/SystemConfiguration/
nano com.apple.Boot.plist
------------
editor opens the configuration file, add these two lines (up your config):
<key>Graphics Modes</key>
<string>1600x900x32</string>
------------
ctrl+x 
y
enter
Reboot
And it should boot back in native accelerated res.
Currently I'm working on the USBs - this does not work properly...after you retsart there should be a conflict or sth, so I will be soon back

Hope this helps you sort it out! Corssed fingers!

Got hack for USB functionality!

Just remove appleHPET.kext from:

/System/Library/Extensions/

And IT WORKS! All 4 of them! (one eSATA)

So only the wifi remains. Because everything else works perfect.

Here is how to get atheros AR9285 to WORK

1. DOWNLOAD THIS FILE uplo ading.com/files/94fm2e33/IO80211Family.kext.zip/
2. Use kext helper b7, or kext utility to install kext.
3.Fix permissions if using kext helper b7. Dont worry about fixing permissions if using kext utility(it does it automatically)
4.reboot
5.Now you have working Airport

For everyone

if you are using the hp 4520, i5 or i3 you will want to use "regular" iboot cd and install retail 10.6.3 SL. This will give you the native resolution of 1366x768x32@60, without changing the pbios in the script.However, I for the life of me cannot update. I always get an early restart or a kernel panic no matter what I do. Any help here? any help at all? please.
