Como limitar o número de produtos mostrados no bloco de novos produtos? via cms / pages / design / XML de atualização de layout

<block type="catalog/product_new" name="home.catalog.product.new" template="catalog/product/new.phtml" >
   <action method="setColumnCount"><count>5</count></action> 
   <action method="setLimit"><limit>5</limit></action>
</block>

setLimit não funciona, nem

<action method="setDefaultGridPerPage"><limit>5</limit></action>

ou:

<action method="setData"><key>limit</key><value>3</value></action>

ou:

<action method="setProductLimit"><count>5</count></action> 

ou:

<action method="setProductsLimit"><count>5</count></action> 

ou:

<action method="setProductsCount"><count>5</count></action>
