No, it's not. I am well aware of what's in the ATA spec.

Not true.
Gujin also do the absolutely needed setup of the IDE hard disk which is to freeze
the password system _and_ the config system of all the IDE hard disks present, so
that no virus can put a random password and send you an E-mail with the address
where to send the money to get the password to unlock the hard disk and so access
again your data. Again, freezing means no more modifiable until next power cycle,
so IMO it is the job of the bootloader to setup the hard disk, before running
anything like Linux, a commercial OS, a bootable CDROM...
This is totally broken, and I am going to strongly recommend that no one
use this software.
It is the OS responsibility to do this. As a simple example, when the
libata ACPI patches are merged (soon), libata will send BIOS-specified
taskfiles to the device -- including the hard drive password, if any.
Then it will freeze the settings.
Gujin's behavior will prevent the user from accessing their data, if
they have protected it via BIOS.
Gujin is assuming that your hard disk are accessible by the documented ATA ide
system, and some (or all?) IDE SATA interface have (volumtary?) broken
implementation: they are not IDE register compatible.
More evidence that Gujin is completely broken.
Host controller programming interfaces have _always_ been variable. PCI
IDE standard was never a requirement for all host controllers, indeed
such a requirement would be stupid, and widely ignored.
Modern SATA controllers are all FIS-based, and are not (and should not
be) limited by the legacy IDE register programming interface.
