It would do all the things to go into sleep and wake instantly. I ordered another card, different from the one on and here and still no joy.
After checking the console upon wake and seeing it was the bluetooth decided to wire everything through USB plug using a couple of diodes to reduce the voltage down from 5v to 3.3v everything now works great. The only thing I can't test is waking from Bluetooth as I have no mouse or keyboard in a bluetooth variant. Wake does happen instantly and I have been using dark wake in my boot.plist to cure the double click wake issue.
I can only suspect it is some sort of power management issue with my board GA P55 USB3. The USB and the PCI Express must power off at different times, making it think some activity has happened.
With my second card I managed to get one with the plug and cables which eliminated the fiddly soldering.
I don't think it was a power management issue with your motherboard. Those cards are designed for 3.3v and hooking it directly to the USB header on the mobo gives 5v. Running it through a USB hub, using 2 1N4004 diodes, or a 5v to 3.3v regulator should take care of that.
I unplugged bluetooth and I put system to sleep (it works ok without bluetooth). Then I checked with a tester all the 3.3v pins on the motherboard power connector. All of them are off. So there is no 3.3v power on my board during sleep (instead, 5v is present on pin 9).
Therefore: sleep doesn't work because the bluetooth module is not powered during sleep. If I had an airport card in my MiniPci to Pci adapter, it would probably be powered to allow wake on lan. So the solution are:
1) Adding the airport card as described in the original post.
2) Drawing the 3.3v from the USB hub with diodes or voltage regulator.
Do you think it's correct?
I don't think adding the airport card will make any difference, it didn't for me, I would try the USB power route and see what happens, the cost is minimal and then you will know. Mine is working fine and the bluetooth seems to reconnect almost straight away from wake.
