BIOS settings: Multicore Support = Off
Installed the Hazard Snow Leopard 10.6.1- 10.6.2
No other modifications used on initial install. Just the 10.6.1 and 10.6.2 updates.

Used Nawcom's 10.6.6 Legacy Kernel and Empire EFI's Legacy Chamelon Bootloader RC2
I had to turn the multicore support off because when its on, Mac runs suupppppeerrrrr slow. You can either turn the Multicore off or type "cpus=1" during efi boot.
If anyone finds out how to permanently get multicore support for the Dell D620, please reply. Other than that...
Works like a charm still get a rare and random kernel panic and the sound is scratchy at times.
FOUR successful installations with the config used above. :)
