A few weeks ago I helped out on a project creating some featureeventreceivers to dynamically add webparts to pages. Because of time-restrictions I didn't have the time to look into a weird problem we encountered..
We experienced a problem when adding a listviewwebpart from code in which we don't want to display the toolbar. (aka toolbar = none from the Edit Shared Webpart menu).
Now, my fellow team-system-guru Marcel :-) decided to turn over to the wonderful world of SharePoint and came up with a solution!
On his blog he posted the code-snippet to effectively remove the toolbar from a listviewwebpart. The solution looks like a hack..but apparently this is the only way to achieve this..

Great work Marcel!
