I'm not talking about how to install basic software to get the desktop working (there are many topics that do this job). Just for inspiration, I used hazard DVD 10.6.2 to install the OS, then I have Installed the vanilla SL and upgraded it to 10.6.8 from software update.
hp dv6821el is a very compatible machine so I suggest to take advantage of this thing and install Snow Leopard on it. I've also installed ML but, believe me, SL is much much fast and smooth...
Everything is working (except for SD.. mine is broken so you are free to test..)
webcam has to be activated using camera control App (after you open Skype open also this application)
Maybe you will prefer VoodooPs2 for touchpad (free to test it to).. Sometime ApplePS2Controller doesn't works well, specially after unespected shutdown (because of battery low ).
DSDT includes a lots of patches (battery, backlight, audio, shutdown, smbus, lid....).
Only IOPCIFamily from 10.6.2(hazard) permit to get the sleep (it makes the installation a bit less vanilla and give me some random kernel panic I guess..)
I changed the model to MacMini2,1 so I got vanilla powermanagement combined to dsdt patch (processor T5550 is used only by MacMini2,1)
Added OpenHaltRestart.kext to get reboot (if somebody knows a better fix please, share it!)
legacy dummy for IOATAFamily maybe is useless (I don't have notebook to test)
