Log:
When flipping the first entry in the qinfifo with the "next queued SCB",
we must also inform the card of this change. Otherwise the sequencer
will traverse a corrupt list of SCBS. The side effects of this problem
were unknown SCBs completing in the qoutfifo or worse yet, panics due
to sequencer interrupts that referenced what, to the kernel, were invalid
SCB ids.
