Not to my knowledge.  Daniel Jacobowitz (drow) has discussed it a little,
but I have not heard much about it lately.

Not again......It must be that Aussie English :-)

I believe we have tied the BDI context switch configuration option to
allowing external debugging by ensuring the kernel doesn't mess around
with the debug registers.  We have at least discussed doing it.  As
long as we properly context switch the debug registers, all of the software
modes should coexist happily.

Thanks.
