Hey Oscar,

It sounds like you're wanting to access the back/forward list  
directly.  getHistoryLength() and historyURL() are *primarily* in  
FrameLoader for use internal to FrameLoader.

Since the back/forward list is more a property of the Page you should  
be manipulating it from there if you need more advanced information  
from it.
Like you already pointed out, this is cake - anywhere you have a  
frame, you just call frame->page()->backForwardList()
