Unfortunately, to my knowledge, no.  There is a document that
describes how to write a pseudo-device for NetBSD on www.netbsd.org
which describes the mechanics of hooking a device into the kernel -
the only real difference between a pseudo-device and a real device is
the probe routine and the fact you actually have to deal with some
hardware.  I do have a document that someone else wrote that is the
start of how to write a PCI driver, I hope to fix this up one day and
get it up on the NetBSD web site too.
