Instead of including a number of tombstones per row, you might might just
have a dummy tombstone location (use zero, for obvious reasons) that signals
the end of that row.  It would work something like this:  load the position
of the next tombstone on the row.  If it's non zero then loop...otherwise
the row is done.  This would keep you from decrementing a tombstone counter
on each row. I'm not sure exactly what your display will look like, but it
might save you a cycle or two.
