Søren Schmidt 27da7e6f24 Finally first shot at a driver for the Promise SuperTrak SX6000 ATA RAID 
controller. Some testing has already been done, but its still greenish.
RAID's has to be setup via the BIOS on the SuperTrak, but all RAID
types are supported by the driver. The SuperTrak rebuilds failed arrays
on the fly and supports spare disks etc etc...

Add "device	pst" to your config file to use.

As usual bugsreports, suggestions etc are welcome...
