You do realise Hollowtech, refers to how the crank arms are just that, hollow. Hollowtech 2 refers to cranks that use hollow arms, with the BB axle integrated into the drive side arm and uses an external BB.
The BB you're talking about may work with the original hollowtech cranks, but its an Octalink BB.
Oh and the Deore/LX/XT Octalink BB's were different to the XTR/Dura-Ace BB's, so it might look similar but the splines are slightly different.
