Dear Dnn-fellows

Perhaps this is the solution.

First
In dnn 4.0.3 and later... you can choose a menu provider, for instance:
ProviderName="SolpartMenuNavigationProvider"
ProviderName="DNNMenuNavigationProvider"
Dnn support both (and others...).

Second
In the solpartmenu you could use for instance:
rootbreadcrumbarrow="RtMnItBrArrw.gif"
submenubreadcrumbarrow="SuMnItBrArrw.gif"
These setting you can't use anymore...

Third
Instead of this two properties you've to use
NodeLeftHTMLBreadCrumbSub (HTML to display to the left of the node that resides in a submenu and is a breadcrumb)
NodeRightHTMLBreadCrumbSub (HTML to the right of the node that reside in a submenu and is a breadcrumb)
NodeLeftHTMLBreadCrumbRoot (HTML to display to the left of the node that resides in the root and is a breadcrumb)
NodeRightHTMLBreadCrumbRoot (HTML to the right of the node that resides in the root and is a breadcrumb)

I'm still surprised that the rootbreadcrumbarrow works...

There is a lot of work to do to manage the menu's (solpartmenu and dnnmenu). I hope that we can help each other.
