Now You are KING on T61 just need one litlle step to enable wakeup on bluetooth
NOW I am the king.
I fixed bluetooth wakeup by starting with a brand new, untouched DSDT. I booted into OSX without a DSDT and extracted it myself. I added the two devices you added to yours, and sleep works without issue. Bluetooth wakes up too.
I installed my WiFi card and it works out of the box.
The last issue I have is Fn+F4 does not sleep the system. It almost sleeps, but locks up before completing. Fans and hard drive stay on. Do you have a patch for that in your DSDT?
EDIT: One more thing - did you get iCloud to work? I can't get it working. Seems to be a problem with the SMBios. I tried different SMBios (MacPro7,1 and MacPro4,1) and they both let me do iCloud, but I cannot sleep anymore.
EDIT 2: I fixed iCloud
Use smbios from MacBookPro8,2 instead of MacBookAir4,1! Also, I fixed Airdrop by using this line in terminal:defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1
I still need a Fn+F4 fix though. Maybe next week I will try Mountain Lion
EDIT 3: Spoke too soon
MacBookPro8,2 killed sleep as well. But I was able to logon to iCloud with it, and then switch back to your smbios which works with sleep.
