[PATCH] reserve resources specified by the PnPBIOS properly

A bug prevents the PnP layer from reserving some of the resources
specified by the PnPBIOS.  As a result some systems will have
unpredicable (random crashes etc.) problems because of resource
conflicts, especially when PCMCIA support is enabled.  This patch
fixes the problem by ensuring that the proper resource data is
reserved.
