Have a look at device drivers for just about any PCI device in your
/usr/src/linux directory. Examples abound there. I usually browse around
/usr/src/linux/drivers/net and find something that looks familiar. This
works better if you are running an older kernel, as the kernel handling of
the PCI bus was beefed up in 2.4 (as I understand it) thus vastly
simplifying PCI device drivers and removing a good source of information for
RTLinux developers. Still, even on the 2.4 kernels, you will find plenty of
old-style device drivers to parrot.

You get them from the configuration registers, as you posited
earlier.
