It is true that  the  BDM  debuggers  usually  don't  understand  the
address mappings very well as soon as the MMU has been turned on, but
it is NOT TRUE that "BDM's will fight with the kernel".

So the BDM debugger might not be too helpful while Linux is  running,
but it does not cause any problems if you configure it correctly:

Depending on your settings of the Debug Enable Register (DER) you can
run  Linux  with  a  BDM  debugger  attached  without  any  problems;
0x6002000F or 0x2002000F might be useful settings - depending on what
you like.
