Not all in one place. Read:
Documentation/pci.txt Documentation/DMA-mapping.txt Documentation/IO-mapping.txt and the attached document, regarding netdevice member locking rules.
Your best reference is other PCI ethernet drivers. grep for 'pci_module_init' in drivers/net/*.c of the most recent 2.4.x kernel, for a good start.
Also... before you start thinking about gunking-up your driver with all sorts of backwards-compatibility code... remember that most 2.4.x drivers can easily be backported to 2.2.x with a few magic macros and static inline functions. I have an example of this sort of thing at http://gtf.org/garzik/drivers/kcompat24/
