This is generally not considered a useful feature for most people, so 
it's not something that FreeBSD is naturally able to do =-)  You'll need
to hack src/sys/cam/scsi/scsi_da.c so that when it issues a 
READ_CAPACITY command, it ignores the results for your particular drive
and instead substitutes a synthetic 18GB value.
