I've done this by having requests to allocate memory propigate up the tree. We'll see how well this works and reevaluate if it isn't working well. Also initialize ptr in the tuple. As well as minor reorg of memory allocation. Likely need to do similar things for I/O when the time comes. I've move all defines from pccardchip.h into pccardvar.h and eliminated pccardchip.h.
