Finding null values in a large table

I have a fairly large table (millions of rows) and I would like to be able to find rows that have a null value in a particular column. I know that regular indexes don't contain null values and thus an index on this particular column probably wouldn't help. I believe that bitmap indexes include nulls, but bitmap indexes are supposedly inefficient when the column is too selective. Are there other solutions?
