Strangely enough there are SD to CF adapters out there (Ebay link is to show one, not to recommend the seller) like this one:

Whether it is bootable or not I do not know. But for under $20 it might be worth to experiment with. So... a SD on a CF Adapter to a CF to IDE Adapter. It is works, I'll be damed. Talk about a Frankenstein Machine!
