It's an internal method, so there's no gaurantee that it'll stay in
that class. But it seems the only way to do it, so use it just keeping
that in mind.

In fact I found this code around:

IViewReference ref = getSite().getPage().
	findViewReference(yourViewIdHere);
((WorkbenchPage)getSite().getPage()).getActivePerspective().
	getPresentation().detachPart(ref);
getViewSite().getShell().setLocation(someX, someY);

Not tried if it works though.

wasn't ble to try that out, sorry,
