Well, you are just about right. I am the proud writer of one FreeBSD
device driver though, for the Genius hand-scanner, an ISA DMA device. I
figured everything out from (1) the skinny manual, (2) disassembling
the DOS driver, and (3) the FreeBSD-2.something kernel code. I did
this by immitating what I saw and building my own theories why things
look as they look. And I did get it to work. The only reason why
I didn't program the IRQ controll was that I had no idea how the
device would use it.
I am glad someone finally takes the time explaining to me why things
are done the way they are done. And yes, I finally bought the McKusick
and Leffler's 4.3BSD book just a few months ago.

We'll see about that, but I'm glad that
it's in one language that
I can read :-)
I know... And AFAIK you have no knowledge about NetBSD kernel hacking.
So this would be a good test if that doc is understandable by a
kernel hacking newbie.
