f2a4379534 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.

a7fc696a51 o The move to using VADMIN under vaccess() resulted in some system 
calls returning EACCES instead of EPERM.  This patch modifies vaccess()
  to return EPERM instead of EACCES if VADMIN is among the requested
  rights.  This affects functions normally limited to the owners of
  a file, such as chmod(), as EPERM is the error indicating that
  privilege would allow the operation, rather than a chance in mandatory
  or discretionary rights.
