There is no way to increase the page size. As for workarounds, a common technique is to vertically partition the table into two with the most commonly manipulated columns being collected into one of the tables. Another option would be to store an XML document into a text column.

Another option would be to construct an XML document containing some of the data and store it in a text column. This would probably work best for data that never needed to be searched or manipulated on the server.
