did you try the bootpacl Dell Latitude D830, Intel x3100 graphics card (1920x1200 model) that should be for high resolution screen you might have to edit the org.chameleon.Boot.plist and put your proper resolution.
try a newer chameleon version and see if hd2000 works for you
there is a thread on the forum foe elan trackpad add it to E/E and run a myfix from myHack app
white screen issue is probably because of your graphics not supported at the moment
as for wifi i guess google them for osx compatibility.
alot of older usb thumbdrives have issues with bootloaders. try formating it fat with an mbr partition in diskutility options. then make the myhack pen.... maybe download myhack again in case it was a bad download.
with chameleon 2169 and up chameleon now has persistence with the boot flags you enter at the chameleon prompt it will store them even if you shut down or reboot. make sure you clear your flags. and like herve said if you have multi partitions chameleon will only respond to the org.chameleon.Boot.plist on the partition you originaly installed chameleon too usually the first partition with osx after the small efi one. in my case i have to edit my lion Boot.plist to affect my ML since i had lion installed first.
i know having BT on during install sometimes causes issues on d630/d830

well check if maybe this pertains to your situation https://osxlatitude.com/index.php?/topic/355-d620-docking-station-vga-out/&do=findComment&comment=2648 or maybe you need a dvi to vga adapter but dont quote me on that
then maybe osx is not reading your monitors EDID properly. have you tested with switchresx app? http://www.madrau.com/indexSRX4.html it is trial ware so at least they let you test it.
if your lion detects your hdd then take the ioatafamily.kext from s/l/e and put it in the ML e/e and do a myfix from the myhack installer. but like herve said graphics will have it's issues.
try the same as above a few times. you might have a 4k sector drive. it usually works the first time though running the myhack chameleon install from the booted os.
technically you should be able to build edp on the stable machine for your specific model before swapping hdd's. if it works you can just clone it to another hdd in disk utility or one of those other cloning softwares like super duper or ccc carbon copy cloner
