- *	ISA PNP 1.0 support + access to PCI configuration space
- *
- *	TODO
- *		- implement PNP card configuration (setting io bases etc)
- *		- write user program to drive PNP configuration...
- *		- extend PCI raw access to configuration space (writes, byte/short access?)
- *		- implement PCI access to memory/io space/BIOS ROM
- *		- use c->aux instead of performing lookup on each read/write?
