Did a limited amount of testing tonight. Upgraded to fw_wake_v5. Wake key works fine, and every time. Button assigned to the space bar also wakes up computer. There were also instances where the computer would wake up as soon as it would go to sleep. (for example, I press the sleep button - the power button on my pc - and about 5 seconds after everything shuts down, computer starts up again).
After I was getting instant wake ups, I turned off all the lights in the room and put it to sleep. As soon as I turn on a light, the pc would start up.
Following more testing, I could get it to wake up for pretty much anything. Any button on the remote would work (assigned or not). Small amounts of light didn't, but the screen of my phone did. Unplugging the flirc, and then putting it to sleep, the pc would only wake up with a keyboard press (no random wake ups).
Interesting twist, I reset the firmware back to stable 1.0 and could still wake the pc with button presses (light didn't work). Cleared the config, and it stopped working. Assigned buttons, and every button that was assigned would wake the pc.This was still on stock 1.0.
I have not tested all this on any other pc, but will try to some time this weekend.
