There seems to be a misunderstanding here :
I said that Re-BL does exactly the same as any $10 IR receiver for PS3, appart than with RE-BL, you can power on the PS3. (Your last question was if a $10 adapter was sufficient, not if RE-BL works with Sony PS3 PUC item!!) 
If you want to use an USB adapter such as NYKO (which doesn't power up the PS3), you have to choose Sony PS3 on the PUC list.
If you use RE-BL, you need the Sony PS3 RE-BL on your PUC list. It's not there? You just need to ask your dealer to add that specific item on the list.
Note that upgrading your BS3 software doesn't update the PUC List : this list contains a limited number of devices (not all devices, probably for ease of use), which have to be asked to your dealer.
