#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data) .. to 2.2.x and 3.x if people think it's worth it. Driver writers can do this if it's not defined. (The reason for this is that I'm trying to progressively eliminate use of linker_sets where it hurts modularity and runtime load capability, and these DATA_SET's keep getting in the way.)
