no, but before I spend more money (this is getting expensive :-),
does it explain how to write a loadable module that needs to to talk
to a spibus? 
I just downloaded the examples, and the closest is a flash driver, but it’s
not a loadable module :-(

I have plenty of experience writing kernel drivers, I did write the iscsi_target
a while back.
thanks,
