Speaking of the 3B2, has anyone ever seen DMERT out there or had a chance to run it on their 3B2?

The emulation for the 3B2/400 is probably as accurate as it's ever going to be, but the 3B2/700 has very clear and known bugs. One of the things holding back fixing those bugs is documentation in the form of source code. I have the leaked kernel source code for the 3B2/400 ("Version 2") architecture, but I have never seen any kernel source code that targets the 3B2/700 or /1000 ("Version 3") architecture. All I have are the system header files from /usr/include/sys, nothing more.
