peeps, please get this straight. The 5th L3 bridge is not a magical unlocking bridge. It simply enables/disables the high multiplier bit. With it closed (high bit OFF) you can select 5x-12.5x multipliers. With the bridge closed (bit ON) you can access higher multipliers but it depends on whether or not your motherboard offers full support for the 5th multiplier bit.
The notion that the 5th L3 bridge unlocks the processor is just misinterpretation.
When the Tbreds, 2100+ and higher, hit the market on some motherboards they only worked at default speed. (Sometimes they didn't work at all). People later discovered that if they closed the 5th bridge the multipliers could then be changed in BIOS (but only 5x-12.5x). This works this way because XP2100+ (and higher) normally have the high multiplier bit enabled (the bridge is open). Closing the bridge turns the bit OFF restricting the multiplier to just 4 bits (the 5-12.5x multipliers), which older boards CAN understand.
[addition]
We can see this with new low speed Tbreds, 1700+ thru 2000+. These CPUs have the 5th L3 bridge already connected. They need to because their default multipliers are 12.5x and lower.
There's more to it than that, namely multiplier remapping, but that's another issue.
