For ASUSPro B9440UA / B9448UA this is the working solution so far. Still in process of polishing and getting additional services to work. Some useful utilities are also included.
Sound works 100%, screen brightness adjustment works 100% in Control Panel and halfway using Fn keys. Battery stats work via iStatMenu, sleep works (sudo pmset -a hibernatemode 0). For wifi you will need a wifi dongle or a very tiny original apple module.
The problems with booting were apparently due to CPU cores getting out of sync. Got it fixed by installing a relevant kext.
You will need to know how to install EFI onto the hard drive. Use the BootIce utility under Windows to change the default boot record.
Good luck!
