Forrest,

BTW, if you are looking for useful libata projects, it would really be 
nice to resurrect Randy Dunlap's SATA ACPI patches, update those for the 
current libata-dev.git#upstream, and get those in.

libata needs to execute the SATA taskfiles passed to us from ACPI BIOS 
tables, in order to properly set up the hard drive in a way the user 
expects (hard drive password, acoustic settings, etc.).  There should be 
a module option that allows the user to skip this step, and preserve 
current behavior.


Also, a feature Alan requests on occasion:  Call the ATA "set max" 
command to fully address the hard drive, including HPA.  The Linux 
standard is to export the raw hardware directly, making 100% of the 
hardware capability available to the user (and, in this case, 
Linux-based BIOS and recovery tools).

	Jeff
