Yep, all of my 25.40 11Cs have 64 TMDI D-channels.
My 25.30s have pretty much whatever they ordered with them, I would love to get a gun point explantion of the thought process behind ordering 1 TMDI D-channel on a switch they knew they were going to expand in the future.

Then ordering 5 for a single cabinet site with 50 phones.
Thanks for the help. We'll be looking into the keycode thing once the dust settles.
