Yeah, looks very good :)

The primary slave disk is now detected, also the cable is correctly reported 
as 80pin. You can see the updated verbose boot mesages here:
http://www.schmalzbauer.de/statics/silberbuechse/verbose_msg2_pri-slave.txt

But also I get a panic with `atacontrol mode 0`, but not with `atacontrol mode 
1` where no devices are connected to.

Here's the trace (I posted a similar from a Geode box), additional ps results 
are at
