o Clean up driver locking by making the locking semantics between
   2.4.X and 2.5.X almost identical.  Take advantage of SCSI_HAS_HOST_LOCK
   in certain RedHat kernels.
 o Clean up command line parsing.
 o Fix module unload/reload issues stemming from DV thread teardown
   and a missing deregistration of our reboot notifier (lost during
   PCI hot plug integration).
 o Correct precompensation value used for U320 transfers on
   rev A4 hardware.
 o Extract VPD information from the seeprom for potential use
   in sorting controller probes to match boot order.
 o Make LED activity more visible on Rev A4 hardware.
