  I *think* you can do it by creating an exclusion for the "bad
clients" range, and then creating the reservation for each "bad
client".  IIRC, reservations override exclusions.  I know ISC DHCP
works that way, more-or-less (terminology's different, but concept
works).

  If not, dial your scope down in size so that the top end has just
enough headroom for your bad clients.  Create the reservations there,
and there won't be any room left for the dynamic pool to grab
addresses above that point.  This would mean you'd have to adjust your
scope size every time you increase/decrease the number of bad clients,
but dem's the breaks.  You could create reservations for bogus MAC
addresses to help alleviate that.
