083bc8b2cc Add a spin lock that prevents the sequencer from attempting to add an 
entry to the QOUTFIFO when it is full.  This should eliminate the
"Timed out while idle" problems that many have reported.

In truth, this is somewhat of a hack.  Although are interrupt latency is
low enough that we should be able to always service the queue in time,
since each entry must be passed up to the higher SCSI layer for what can
be a large amount of processing (perhaps even resulting in a new command
being queued) with interrupts disabled, we need this mechanism to avoid
overflow.  In the future, these additional tasks will be offloaded to a
software interrupt handler which should make this hack unnecessary.

All resolve to the GIANT_LOCK at this time, it is purely a logical partitioning.

cb02d4da35 Cheap fix for kern/4255. 
If the problem is seen this fix suggests a compile-time work-around then panics.

c0ecffb96b Modify the scheduling policy to take into account disk I/O waits 
as chargeable CPU usage.  This should mitigate the problem of processes
doing disk I/O hogging the CPU.  Various users have reported the
problem, and test code shows that the problem should now be gone.

a1af9248eb Yeah I'm back hacking syscons !! 
Add support for MODEX 320x240x256color with "unchained" adressing, giving
access to all 256K on all VGA's, those with that much memory that is :)

Also make sysmouse use the right resolution in graphics modes.

570dbb53e0 Eliminate frequent silo overflows by restoring the TEST_LOPRIO code. 
This code was eliminated when the PEND_INTS algorithm was added.  But it was
discovered that PEND_INTS only worsen latency for FAST_INTR() routines,
which can't be marked pending.
