There is a i386 remote target that has remote side implementation of
hardware breakpoints (using the Z packets as Andrew said). As soon as
the hardware device necessary for this becomes available, I will submit
some patches to the list.
I also know another target that has access to the debug registers but
does not have the hardware breakpoint implementation. It would be nice
to use its capability of accessing these registers to implement
watchpoints.
