Did you contact Miro?
And /usr/share/examples/drivers/make_pci is pre 4.0.

That's a good start.

It can make certain things clear.

Asking questions is free. =)

If you were using newbus (on FreeBSD 4.0) I'd say bus_space_read_#() to
get the info in the registers our of your chip.

I have to show my lack of 2.2.x and 3.x driver programming. I am
spoiled due to 4.x. I think someone else needs to answer this. Juergen
appears to know 3.x driver programming.
