First of all, many thanks for your help!
I changed your EFI folder by mine, and:
As you said, the wifi/bluetooth card is is still working without those kexts. (My PCIe card didn't worked for me on the Slot 6, and i was installing all i founded to make it work, then i moved it to Slot 5 and it worked and i didn't remove those kexts or didn't do any other test as it worked like that).
For Ethernet i also fail installing the SmallTree-211. Didn't know there was two driver version. And finally i used the 8259 installer.
Now i still have the graphical "problem" when booting, but it seems less than before and still can't change the screen resolution.
Here is the new IOreg file. The EFI is yours, i just added my old serial number.
