have you looked at new row-wise comparison feature (i might be
misunderstanding your problem)?
select some_column from some_table where (cur_date, some_column) <
'01/01/06', 99999999) order by cur_date desc, some_column desc limit
1;
this will give you the highest value of some_column on the abitrarily
chosen date 01/01/06 (assuming all values of some_column are less than
99999999).
