  I'm quite sure the problem is calling the wrong interrupt routine.
When the ibus stuff was added, the interrupt establishment was using the
"ia_cookie" value as an index into the table of interrupts.  Recently
the 3100 interrupt handler changed from direct calls to the device
interrupt routines to using the interrupt handler address in the table
indexed by the "slot number" of the device.  The problem is that
"ia_cookie" for the ibus devices is the interrupt priority, not the
slot number.

  The following patch seems to work, but I'm not certain if the
ibus_intr_establish() call should be using "ia_slot", or if "ia_cookie"
should be changed to be the slot number for the ibus devices.
