ba2ace5164 Change the queueing model used by the controller to drastically reduce 
the time spent at splbio().  We now avoid it unless we are actually
manipulating the command queues themselves.  This doesn't improve
performance noticeably, but should improve concurrency somewhat.

cd4ace0c76 Use the physical block number, not the logical block number, for I/O 
operations.  The latter only works where the partion begins at the bottom
of the disk.  Whoops.

d5a51e03e7 This is a driver for the AMI MegaRAID family of controllers. It all of 
the AMI PCI controllers using the 8LD firmware interface (40LD firmware
will be supported as soon as I have hardware to test with).

These controllers are rebadged by Dell as the PERC, as well as by HP
and possibly other vendors.
