Hello everyone, I'm Carlo from Italy. 
I found this forum while searching on google a solution for the wireless module "DELL1395". 
  
I am very happy, because I can share experiences with you! 
  
I have a DELL D820, that i've found in the garbage and I've fixed it (power supply problems). 
I think it's good computer! I never seen a 15" screen with a resolution of 1680x1050 pixels. Fantastic! 
  
I installed OSX Snow Leopard, because it run very well and I no longer use Windows. 
I installed all the versions from 10.6.0 to 10.6.6 updated with automatic "software update" without any problems. (never have to change any kext) 
  
My DELL D820 is equipped with a Core 2 Duo 2.06Ghz, 128MB nVidia video card, I added a 32GB SSD drive, 4GB of RAM and the wireless module DELL1395. 
In the future I'd like to remove the DVD drive and replace it with another SSD drive and install OSX on a RAID Stripped (RAID(0)). 
I'd like to complement it with a Bluetooth module and a WWLAN. 
  
Thanks to the SSD drive, Snow Leopard boot in 16 seconds and shutdown in 1.5 seconds. 
  
I assembled a boot CD for unattended installation of Chameleon v2.0 RC3, and these kexts in E / E: 
(I tried to use "EDP 1.9", but it doesn't work.. I do not know why! There is something incompatible with my system.)

VoodooPS2Controller.kext 
VoodooPS2Keyboard.kext 
VoodooPS2Mouse.kext 
VooodooTSCSync.kext 
and of course, Extensions.mkext 
  
  
The system works perfectly, Sleep\Stop (without any system password and it work with closing\opening the LCD), the battery icon (!). 
It have only a small problem and a lack: 
The sound, after the sleep is strange, distorted and repeated. 
I'd like to find a solution for the multi-touch trackpad. 
Maybe I'm opening a discussion in the appropriate section. 
  
Bye! 
Excuse for my bad english! 
  
p.s. Thanks to  crc-error404 for the D820 BIOS A10 rebranded with the Apple Logo!
