9to5Mac reports that MacSales has discovered that with an EFI update, older MacBook Pro Unibodies can accept full 8GB of RAM. I'm delighted with this news. This is discussed in another thread, but I thought it would delight other older MBP owners hoping to get a bit more from their previously 'crippled to 4GB RAM machines'.

How do you ensure your Late 08 MacBook/MacBook Pro can address 8GB of RAM?
First, you want to make sure you have one of the affected models:
MacBook 13.3″ 2.0GHz and 2.4GHz
MacBook Pro 15″ 2.4GHz (All)
MacBook Pro 15″ 2.53GHz model w/ExpressCard Slot (Late 2008)
MacBook Pro 15″ 2.8GHz model w/ExpressCard Slot (Late 2008)
Next, check the Boot ROM Version in your System Profiler.
MacBook Pros with a Model ID of MacBookPro5,1 should have a Boot ROM Version of MBP51.007E.B05.
MacBooks with a Model ID of MacBook5,1 should have a Boot ROM version of MB51.007D.B03
Machines with other Model IDs are not affected and dont need an update.
UPDATE:
Crucial UK sell this 8GB kit for £71.99.
