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.
