We ran into this issue when upgrading to NHibernate version 3.3, but for a different reason...whitespace. We had a lot of sql strings that looked like this:

var sql = @"
select col1 from MyTable";

or:

var sql = @" select col1 from My Table";

These resulted in the "The query should start with 'SELECT' or 'SELECT DISTINCT'" errors because NHibernate doesn't trim the string before validating it.

We created a new dialect that trims the string first to get around this:

public class Sql2008DialectCustom : MsSql2008Dialect
{
  public override SqlString GetLimitString(SqlString queryString, SqlString offset, SqlString limit)
  {
    var trimmedQueryString = queryString.Trim();
    return base.GetLimitString(trimmedQueryString, offset, limit);
  }
}
