I have a DV7-6163us. It has core i7 2630 processor, 6GB ram, Intel HD 3000, USB 2.0 and 3.0, Intel wifi, webcam, HDMI out, Synaptics trackpad, Beats Audio. After a lot of effort, I had it working with 10.6.8 with everything except graphics and HDMI out. I installed Lion via Kakewalk, and I was able to get it to boot Lion using a lot of kernel flags. No graphics or 64 bit anything. I had to use cpus=1, arch=i386 and GraphicsEnabler=no.
I reinstalled using this install disk, and it gives me a little better version of Lion. I think I had to use cpus=1 and GraphicsEnabler=no to install, but that was it. It installed nicely. After install, it took a while to get it to boot. To get it to boot, I have to use the following kernel flags:
cpus=1 PCIRootUID=1 arch=x86_64 GraphicsEnabler=no DSDT=yes -v -f
The Intel HD 3000 is recognized. I still don't have HD graphics, although I have 64 bit going. I have 1024x 768.
I tried running it with the base install, i.e., what I had right after install completed, then I transferred the DSDT, smbios.plist and org.chameleon.plist files from the install disk per instructions, then I tried using my own DSDT that I previously used with SL. It seems to run pretty much the same no matter whether I run it fresh, modified with the Extra folder items, or with my own DSDT. For trackpad drivers, I installed the PS2 drivers and for audio, the Voodoo drivers. They are working. My wifi doesn't work, but I use an Edimax nano USB adapter that has mac drivers. It cost $10 at Meritline.com. I was using Chameleon to boot, but it works better with Tony Mac's latest Chimera.
The trackpad is kind of buggy, I think there is a better driver for it that I used before and I have to find it. Sound is ok. Webcam works, not sure about microphone. Battery is recognized.
USB 2.0 works. USB 3.0 has power, but devices do not load. It used to freeze my system when I plugged into the 3.0 ports in SL, it does not do that any more.
No sleep, but I will try the speedstep fix mentioned above and see if that helps.
Thanks to all who participated in this thread, especially the OP. It helped a lot.
I am close, but eventually, it would be nice to be able to start without kernel flags and to have full graphics. I will keep following this thread to see if we get there.
