Almost all of those are the stupid sysdev_class and sys_device stuff.  I
_really_ want to get rid of those as they should be a "normal"
device/driver/class.  I think Adam Belay has some patches he is working
on to get rid of these, but I do not know the status of them.

Anyway, they are static structures, so my fix will keep them from
oopsing.
