"/lib/udev/ata_id --export /dev/sdX" does the right thing and thus udev uses
the right ID string. I dunno how difficult it would be to plumb that
information from udev to hal tho.
The kernel can't provide full string due to the difference between SCSI and
ATA. ATA model ID string is simply longer than SCSI model ID string. ATA
devices appear as SCSI devices and libata has to report truncated model string
to SCSI midlayer when queried via INQUIRY SCSI command, which SCSI midlayer
reports to the userland.
To work around this, SCSI/ATA translation standard defines VPD page 0x83 to
carry ATA specific identification information which libata implements.
