Got the same computer
Everything works out of the box (except wifi...i changed my card with a airport compatible one)
Make your pen drive following tutorial "Install Lion on a supported machine" (with a 10.7.0 dmg image...not a 7.2)
First BOOT start EDP2.2 install kext (1-12) and Chameleon and everything you need/want (for example Fix Hibernate voodooHDA PS2 ect..)
Before making a update to 10.7.2 make a change on your DSDT.aml to protect you against Blackscreen
By modding
Replace:
QUOTE
"device_type"
Buffer (0x0D)
{
"NVDA,Geforce"
}
with:
QUOTE
"device_type"
Buffer (0x0C)
{
"NVDA,Parent"
}
One important thing, if you got a Hard Drive with 4K cluster
To avoid BOOT: Error
Make a Ubunto Live CD and type the following terminal command
sudo dd if=boot1h of=/dev/sda"x" bs=4096 (x = your OSX partition)
download boot1h on following link
Issue 4K Chameleon
Good Luck
