I created a list from a custom list definition, and wanted to add the list as a webpart to a page defined in my custom site definition.
In the sitedefinition, it was enough to declare the BaseViewID property to define which view I wanted the list to display on the webpart.
<View List="Lists/LinksDocLibs" BaseViewID="4" WebPartZoneID="Left" WebPartOrder="2" />
Then, in the list definition, I modified my selected view to show the FreeForm toolbar, which should only display the "Add new item" link underneath the webpart.
<Toolbar Type="FreeForm" Position="After" />
However, when using this, the "Add new item" link is not shown. To accomplish this, we have to insert some HTML into the <Toolbar> tag. Do it like this:
<Toolbar Type="FreeForm" Position="After">
<IfHasRights>
<RightsChoices>
<RightsGroup PermAddListItems="required"/>
</RightsChoices>
<Then>
<HTML>
<![CDATA[<table width=100% cellpadding="0" cellspacing="0" border="0">
<tr><td colspan="2" class="ms-partline"><img src="/_layouts/images/blank.gif" width="1" height="1" alt=""></td></tr>
<tr><td class="ms-addnew" style="padding-bottom:3px"><img src="/layouts/images/rect.gif" alt="">
<a class="ms-addnew" ID="idAddNewItem" href="]]>
</HTML>
<URL Cmd="New"/>
<HTML>
<![CDATA[" onclick="NewItem(']]>
</HTML>
<URL Cmd="New"/>
<HTML>
<![CDATA[',true);return false;" target="_self">]]>
</HTML>
<HTML>
Add a new item
</HTML>
<HTML>
<![CDATA[</a></td></tr><tr><td><IMG src="/_layouts/images/blank.gif" width=1 height=5 alt=""></td></tr></table>]]>
</HTML>
</Then>
</IfHasRights>
</Toolbar>
There, that should do the trick 
Starting with this, you can also easily customize your layout as you can change the entire HTML markup for the Toolbar template 
Have fun with it
