Sleep/wake in SL works without any changes even without dsdt.In Lion I had to swap AppleACPIPlatform.kext with that from SL,to get wake working.Issue-In kernel log there is message "USB Notification: The device "HubDevice" @ 0x1d100000 has caused an overcurrent condition. The port it is attached to has been disabled" although all usb ports works fine.Some time after booting OS appears this message
