I copied more than my fair share out of Charles' efforts.  More

I have managed to load and (partially) boot an Inferno kernel (was the
speediest thing to do - tested BOOTP and TFTP in one operation) with
the driver, so I think I have the rough idea right.  It needs a lot of
cleaning p, but should be ready today after some cleaning up.

Really got hooked on that 97c didn't I?  It's a 79c960 I'm working
with.  I can't test the other controllers, but guinea pigs and/or
sample hardware are encouraged to come forth.

Well, seeing as I've reached a milestone, I'll go ahead with the
second phase of a 9/pc driver and I don't think I'll need any bounce
buffers or DMA complications at this stage.  Maybe once the tidying
up is underway I'll try to generalise the DMA setup operation: at
least detect conflicts.
