OS X 10.7.3 is working well on Dell Inspiron 6400. Everything works except sleep. I could not test sleep as my power button is broken and I use the MediaDirect button to start my laptop.
I have not used any DSDT or injection.
I have not had a single KP so far.
Please note that upgrading to 10.7.5 and above will break the OS, it will boot to a blank screen. if you patch the AppleIntegratedFrameBuffer.kext, it will panic as the patched version is not supported beyond 10.7.4.
To get it to work on 10.7.4, you need to patch AppleACPIPlatform.kext with the one from Snow leopard 10.6.8 and also patch the AppleIntegratedFrameBuffer.kext.
Since I was happy with the performance of 10.7.3, I decided to stay on this version.
All the native OS X softwares like Aperture, iWork etc and third party softwares like Adobe products, office for Mac etc. run without any issue.
My Inspiron 6400 configuration is as follows:
Intel Core2Duo 7200 with 64bit support;
Intel ICH7 family chipset optimized by Dell
Onboard Intel 945GMA video driver with 64MB shared memory;
(1680x1050 full resolution, QE/GL everything works including mirror) : patched with AppleIntegratedFrameBuffer.kext (version 1.4.20.28)
4GB 667Mhz DDR2 RAM,
RICOH R5C822 memory card reader (in-built),
(works well with patched VooDooSDHC.kext)
2-port UBS 3.0 ASMedia 1042 Express Card in ExpressCard slot;
(works with native AppleUSBHub.kext and patched CallDigitUSBxHCI.kext), CallDigitFastO.kext is optional but recommended)
500GB SATA HDD;
Onboard Broadcom 440family ethernet;
(works with AppleBCM400.kext)
Broadcom BCM4322 mini-wifi card,
(works Out of the Box, no need for any additional kexts)
Sigma Tel Stac9200 onboard Audio Device :
(Works with VooDooHDA (version used 2.7.2)
Trumobile 350 bluetooth card :
(Works OOB)
Slot loading CDwriter/DVD ROM
I will attach a list of kexts that I have used and also the Extra folder which includes my edited chameleon.plist and smbios.plist.
For the patched kexts, you may need to patch with your Dev-id and Ven-id of your hardware.
Prerequisite:
You need to find a working OS X Snow Leopard machine to create a bootable USB stick of OS X Lion patched with AppleIntegratedFrameBuffer.kext from here.
Any windows software like MacDrive to access OS X partiton from windows to edit the Extension folder after fist install.
You will need to edit the info.plist of some of the kexts to insert the Ven-id and Dev-id of your hardware for full compatibility.
I can post a full tutorial on request.
I am multiboot (chameleon, stolen and rebranded)ing with Lion/Linux/Windows 8/Windows 7 and Windows XP from a single drive.
